Few things are as delightful as Elton John singing with Miss Piggy, or the Spice Girls teaching a science class.
Elton John on "The Muppet Show" (1977)
In what's gotta be the most delightful three minutes to ever take place on Earth, a very stylish Elton John and Miss Piggy sing duet on "Don't Go Breakin' My Heart." He may be the only guest to ever wear more pink and sequins than she does.
Biz Markie on "Yo! Gabba Gabba" (2010)
In which Biz Markie recommends that children punch themselves in the throat repeatedly.
The New Standards on "The Choo Choo Bob Show" (2012)
This is seriously like a real-life version of that SNL sketch where Fred Armisen and Kristen Wiig are a terrible holiday music duo who make weird vocalizations instead of singing. Thank you, Minnesota public access.
R.E.M. on "Sesame Street" (2010)
FURRY HAPPY MONSTERS FEELING GLAD. Can you even deal with this new rendition of the classic R.E.M single, partially sung by puppet pals?
