My favorite is "Did you motor boat her?!", and "You motor boating son of a b*($#", also my friend often randomly says "She was my first Asian!", at completely inappropriate times.
"Please don't take a turn to negative town." "I'm gonna go see Dr. Finklestein and I'm gonna tell him we have a whole new bag of issues. We can forget about mom for a while." "I got a stage five. Virgin. Clinger." "Tattoo on the lower back? Might as well be a bullseye." The last one is my favorite.
