Hey man, you know Bob from finance? He is a total Dick Junky. I just caught him looking at my dick in the bathroom, licking his lips and sweating.

You know that dude Dedo from Human Resources? Man oh' man, I saw him bend over in a skirt without panties on. He had total-Pink-Puckered Buggle Gum. I bet you I could chew that shit up and blow bubbles.
