incorrect goof
imdb says: Continuity: When Dave and Andrew are erasing each other's favorite things, Dave hates away Andrew's controller. In the next scene, Andrew uses this controller in the video game challenge.
this is incorrect, the controller Dave makes dissapear is a third-party xbox controller. probably 'madcats'. the controller he uses in the video game challenge is a regular xbox controller.
i'm sure if playing video games is one of their favorie things to do, they'd have more than just 2 controllers. they'd have more as 'backup' controllers. like dave said when he was about to bury it, it was his 'lucky controller'.
