I think all three guys have definitely sh.it on their heads, but the question is how one of the guys notices that he has sh.it on his own head.Antiphon said:He can't figure it out.
Here are all the possibilities:
0 guys/w sh.t. Nobody laughs.
1 guy/w sh.t. The other two laugh.
2 guys/w sh.t They all laugh.
3 guys/w sh.t They all laugh.
There's no way to infer that you also have sh.t
just because all three of you are laughing. You
may or may not have it.
