Adam's Apples is a show choir based at NYADA in New York.
When Kurt is caught looking at their sign up sheet, Adam, the lead singer of the group, introduces himself and asks Kurt to sign up. Kurt is reminded of Rachel telling him not to join, because it's social suicide, but Adam won't go down without a fight. He drags Kurt downstairs and Kurt laughs and enjoys the performance of Baby Got Back, sung by the "Adam's Apples." The group is full of unique people, wearing different hairdos and clothes. They pull off awkward and hilarious dance moves, making Kurt laugh a lot.
Adam kicked Kurt out after he found out he was engaged.
