Mitt is the leader of the Mighty Jocks employees from a neighboring sporting goods store who come into the Burbank Buy More and take over the Buy More's Home Theater Room to play a football video game.
Lester, the then assistant manager, ordered Morgan to kick Mitt and the rest of the Mighty Jocks out of the home theater room for making a mess. Morgan goes in and tries to convince them to be quieter and to tidy up after there selves but Mitt doesn't listen and shoves a sandwich into his pocket.
The Buy More staff decide that they can get rid of the Mighty Jocks and avoid confrontation by switch off the power to the home theater room but this only angers Mitt as he was in the middle of a game winning drive.
