Well clearly your brother is a homosexual whereas you are a normal healthy male :ma<b></b>ho:
edit: Or a woman in disguise. The plot thickens?
He would talk about an imaginary field trip where he ate GARBAGE? It sounds like he might have had some mental problems.
Either that, or he enjoyed fucking with you.
Which would support the “homosexual” theory. 
HE didn’t eat the garbage, the garbage men did. And they had trash fights were they got garbage and threw it at each other. But it was all made up anyway so it doesn’t really make a difference. D:
oh man, that sounds like one hell of a field trip.
lol is all that needs to be said.( I think that that study was done only on drunken men without any control experiment. Or am i just good like that?) I R CONTROLLLLLL
