A stack of crates rises from the floor, holding up one child and exciting another. The boy on the crates stands silently while the other questions aloud “aren’t you going to stop us from doing the milk crate challenge?”
A woman in a towel, holding a cup, passively watches the pair, slowly and deliberately takes a sip, and finally lowers her cup again, before simply replying “nope.”
No idea how many were actually done, if I recall it was making large pyramids of milk crates and attempting to climb them. Largely resulting in the structure collapsing and people getting banged up.
