Overheard Conversation of the day...

two guys talking to a girl on the bus:

guy1- "are you a lesbian, or a bisexual?"
girl- "I'm a bisexual"
guy2- "thats when you're gay and a lesbian, isn't it?"
mix of many words from guy1 and girl of which the basic point was- "gay and a lesbian? That's the same" and a bit of "wouldn't you have to be a hermaphrodite!"
girl- "It's when you're straight and a lesbian"
guy2- "straight and a lesbian- how does that work?"
girl- "it's called bisexual... ...remember?"
guy2- "oh, um, oh yeah...!"

based on hearing this my brother and I came to the conclusion that hermaphrodites have to be bi.
