Hallmark would make "Sorry, what was your name again?" cards.
Breaking up would be a lot easier. A smack to the backside and a "Nice hustle, you'll get 'em next time" would pretty much do it.
Any fake phone number a girl gave you would automatically forward your call to her real number.
At the end of the workday, a whistle would blow and you'd jump out your window and slide down the tail of a brontosaurus and right into your car like Fred Flintstone.
