Is it vein to do callbacks to my own comics? Probably.
I had three other version of this comic and wasn't sure what the best one was, here are the other versions for anyone who cares.
Differences start after "What? No. It's just an expression."
Woman: An expression? You expect me to believe that? For Pete’s sake! Man:… Man: Who the HELL IS PETE!?!?
Woman: You expect me to believe that? Man: Oh for Pete’s sake! Woman: THERE’S A PETE TOO!
Woman: You expect me to believe that? Man: Oh for Pete’s sake! Woman: How did you know about Pete?
