I'm looking forward to when the others say something like, "How long are we supposed to just sit here watching this? I know we're unconscious, but come on..."

If you look at 1447, the unconscious people are on a food run.

So... Is normal in D&D characters that imitate Donkey Kong?

There's a prestige class called the "Hulking Hurler" designed around tossing large blunt objects at your target that easily winds up with damage numbers more easily expressed in scientific notation.

It's meant more for giant-y types to chuck rocks around, but Adventurers being who they are, I'm certain that there have been many a wagon, tree, and barrel hurled.

House, castle, moon, neutron star...

I had a warforged Eldritch Knight in 5e whose lifting capacity was five digits.

Please tell me you took the Tavern Brawler Feat with that build.

Of course. My DM even ruled that it stacked with the Iron Fists feature of the Juggernaut subrace with each increasing unarmed damage one die size, so he punched at d6 + STR damage. With brass knuckles, it increased to d8 + STR.

Mind sharing how you achieved that? Even with a Belt of Storm Giant's Strength setting the ability score to 29 (an ability score otherwise impossible for PCs) and taking 6 levels of Bear Totem Barbarian for the doubled carry, push, drag, and lift values, after using the enlarge option of Enlarge/Reduce (which will further double those values) and the not-rules legal Powerful Build which Warforged have no access to, that's still only dead lifting 6960 pounds if you've got no weighted equipment on (as any equipment on you counts against this value so unless you drop everything you won't even hit this record), and your character's speed is reduced to 5 feet and generally can't do much while standing/shuffling around with this weight over you like a muscle-headed idiot. The only feasible way would be to stack the Bull's Strength option of Enhance Ability but you're already presumably concentrating on Enlarge so that's out as a consistent option as you'd have to get one or the other from an allied caster.

This all falls apart though since Warforged do not have the Powerful Build racial trait that Bugbears, Firbolgs, Goliaths, Loxodons, and Orcs have or the Equine Build trait that Centaurs have which is functionally similar. Thus Warforged can not legally break that 6960 pound limit, and only reach that with outside assistance.

That's because there's very few ways to go above the hard cap on PC ability scores of 20. There's the Barbarian level 20 capstone that increases their Strength and Constitution Scores and the corresponding Score Caps by 4 such that the new Score Caps for a level 20 Barbarian's Strength and Constitution are 24. Then there's the Artifact Tomes and Manuals which each only raise the Score Cap and actual Score of one Ability Score by 2, but if your DM is handing those out like candy something is very off from the default. Lastly there're the Belts of Giant's Strength with the Storm Giant version being the most powerful and it sets your Ability Score to 29 while attuned and worn, ignoring your normal Score Cap.

I was using the Unearthed Arcana Warforged at the time, Juggernaut subrace, which had the Powerful Build feature (+1 size category for carrying), I took the Brawny Feat (+1 size category for carrying), and later in the game I was allowed a third party Feat Legendary Strength (req 20 base Strength, +1 size category for carrying). So at base level, I was carrying and lifting as a Gargantuan creature (x8) with 20 strength.

I had a couple of magic items. One was the Amulet of the Bear which granted the x2 carrying capacity bonus of the Path of the Bear feature. Another allowed me to cast Bulls Strength once a day without needing concentration for another x2 for 1 hour.

And finally I could cast Enlarge for another x2 for 1 minute.

Never got a belt of Giant strength, but my base lifting was x16 and I could boost that to x64 if I really had to.

The only class that can make the huge LA of a centaur worthwhile. Because the benefits of being both large and quadrupedal for the purpose of lifting capacity far outweigh the cost of LA 2 and 4 required racial levels

This probably means she is confident she can throw things with more strenght than a bazooka.
