The Plan of Backup! A Musical.
(comicgenesis link to the same strip here)
Does this punch line ever get old? OH HO HO! I must be getting old, 'cause I start taking words from like, Centerfold by the J. Geils Band and putting it with the new Scissor Sisters song Invisible Light because that one is new and I haven't memorized all the stuff about Ian McKellan and sailors scaling the walls. I spend a lot of time with music in my head.
I'm not really getting too old for this. ^_^
