Friend: really, i wonder if those little sperms don't go on their merry little way and wonder if they're really entered the right gender, because WHO CAN TELL????? =S
Me: awww, im sure the sperm just go "hmmm i have a tail...that doesnt...guess thats where im heading" and then they look beside them and go "lets race" =P
Friend: haha! they're so naive! apparently the vagina produces antibodies against the sperm, so it'd be more like.... happy racing sperms and then: MISSILE ATTACK!!!! AAAHHHH!!!!! THE ALIENS ARE COMING! THE ALIENS ARE COMING! *blackout*
gotta say, a lot more respect for those sperm, braving a missile attack like that....maybe that's why boys like wars and fighting so much...
