I think the song should be renamed “Five ways to leave your lover”
1) Slip out the back Jack
2) Make a new plan Stan
3) No need to be coy Roy
4) Hop on the Bus Gus
5)Drop off the keys Lee.
And if you really want to get into it...2 and 3 really don’t count....so its like 3 ways to leave your lover...not 50.
