I Love Bad Pickup Lines That Are Funny

Excuse me, where pickup lines ever designed to pick up girls? I thought they were meant to be stupid and funny.
Of course, I'm a nerd so you'll have to laugh at stupid pick up lines having to do with science.

I hear chemists like to do it periodically on the table.

If I was an endoplasmic reticulum, how would you like me, smooth or rough?

If I was a concentration gradient, I'd go down on you.
