I think the Spring Awakening song with the worst lyrics is "My Junk."
Anyway...
"Poor Galinda, forced to reside with someone so disgustingified" - Lucky thing Schwartz was setting a musical in a fantasy land, or else he may have had to find a rhyming word that actually existed!
More Schwartz: "He gives it his all, so why do I sit here, remembering Paul?" and let's not forget "Just a little romance, what else would a woman look for in France?" Something like that. Both are from The Baker's Wife.
"Simon, enough, there's nothing more, don't be a boor" - Ah, Jekyll and Hyde
Basically everything in RENT, to be honest.
Jimmy, what are you doing here in the middle of the night? It's almost 9 PM!
