In Thursday night’s episode of “Glee.” a sing-songy version of Sir Mix-A-Lot’s rap hit “Baby Got Back” was performed and Jonathan Coulton feels like they bit the whole idea from his cover of the song. Coulton might have a case though, the two covers of the hit rap single are so similar,that the “Glee” version included Coulton’s line “Johnny C’s in trouble,” replacing the lyric “Mix-A-Lot’s in trouble” in the original song. After being driven by his angry fans on twitter the night the ‘Glee’ episode was premiered Crouton wrote on his blog “even though they do not credit me, and have not even publicly acknowledged that it’s my version — so you know, it’s kind of SECRET exposure.”
