Dave Grohl put in a guest appearance on ABC's reboot of The Muppets yesterday, taking on Animal in an epic drum battle. The heated exchange sees Grohl and Animal trade some trash talk before going head to head.
Doctors were unavailable for comment as to whether this is part of Grohl's rehabilitation process after he broke his leg falling off a stage in Gothenburg, Sweden earlier this year.
Grohl: "[strikes ride cymbal] Oh what's that, a bell? Time for school."
