annoying jocks in history

today while in ancient history class, which happens to be a class of 40 something students, we were discussing early man which is no problem until one of the two stereotypical jocks shout out "hey sir uh.. how did they discover how to have sex?!" our teacher proceeded to explain that it just happened and it was brain chemistry, then the kid is like "well like how did the figure out where it goes ya know 'cause I'm sure most the people in here *points  throughout the class room* don't know how its done" he and his friend then proceeded to laugh at the horribly lame joke that no one else thought was funny at all. keep in mind the two dumb ass jocks are in grade 12 but are in a grade 11 class... I also don't hate all jocks just these two as i have many jock friends.
