You can't always tell if someone is gay just by looking at them. I've been very surprised in that past. You admit you didn't know him well. I guess that would explain why he didn't tell you about the prank. I'm sure it's not something that he advertised.

Fer sure, they don't always have one sticking out of their mouth!
