Paul Simon's "Fifty ways to leave your lover" only actually suggests 3 ways!

Sorry, Andy, it may not be 50 ways, but it's definitely more than three.

Off the top of my head:
Hop on the bus, Gus
Drop off the key, Lee
Make a new plan, Stan
Slip out the back, Jack
Don't need to be coy, Roy

That's five for starters.
