Just finished watching. The whole episode feels very lame and out-of-character for the show, but there were some nice highlights:
Waitress Titties mmmmmmmmmm
"You must pay the troll toll to get into this boy's hole"
"Little boy, tiny boy, I want to make love to you"
The songs themselves aren't that great, and I'm kind of disappointed in how the adaptation of Nightman/Dayman doesn't make any sense really. I guess that's supposed to be the point, but some explanation of the troll would have been nice. A scene where The Boy/Denis becomes the NightMan would have been good too.
