"Pucker Up or Let Him Snooze" is a song in the Hercules episode, "Hercules and the Big Kiss". Cassandra sings this after Icarus is put into a deep sleep by Hades, and now she must kiss him to wake him up.
Which one am I going to choose?
To pucker up.
Or let him snooze.
Either way I'm in a crunch.
I'll lose my soul!
