A guy walks into a bar, approaches the bartender 
and says; "I've been working on a top-secret 
project on molecular genetics for the past five
years and I've just got to talk to someone about
it." 

The bartender says; "Wait a minute. Before we 
talk about that, just answer me a few questions.
When a deer defecates, why does it come out like
little pellets?" 

The guy didn't know that. The bartender then 
asks, "Why is it that when a dog poops, it lands
on the ground and looks like a coiled rope?" 

The guy again says, "I don't have any idea." The
bartender then says, "You don't know shit! and 
you want to talk about molecular genetics?"
