The muppets managed plenty of goofs while shooting last year's feature film. Here are the highlights.

Also starring the ever-charming Amy Adams and Jason Segel.

RIP Childhood of the Day: Master of subtle terror Graham Annable of Grickle fame takes on the Muppets with an existential tribute to the late Jim Henson.

[superpunch.]

Adorable Duet of the Day: Flight of the Conchords' Bret McKenzie and Kermit the Frog perform "Life's a Happy Song" -- the opening number from the upcoming Muppets movie.

McKenzie, who served as The Muppets' music supervisor, wrote and/or produced all of the movie's original songs.

Questionable Cover of the Day: The Muppet Barbershop Quartet cover Nirvana's "Smells Like Teen Spirit" for the soundtrack of the upcoming Muppets movie.

Up Next: The Muppet Barbershop Quartet cover Nirvana's "I Hate Myself and Want to Die."

[stereogum.]

Another Movie Trailer of the Day: The Muppets pack not one, not two, not four, but... no, wait... four was right -- four parodies into their really, truly, for real this time, final trailer.

Watch the not-quite-mops, not-quite-puppets spoof Paranormal Activity, Puss in Boots, Happy Feet, and one other movie. OK, fine -- it's Twilight. Way to spoil the surprise.
