Have you watched those terrible movie remakes of the cartoon show Alvin and the Chipmunks? There's a reason those movies are so terrible.
Alvin and the Chipmunks are hoodlum gangster chipmunks! Did you notice that in this image?
Look at them! They are uncivilized! Ewwy! The chipmunks wear hoodies and sunglasses and think they are cool! YOU ARE NOT COOL! YOUR MOVIES SUCK!
Not only that, but they completely take over Dave's house in the first movie. Just like juvenile delinquents! Later in the movie, they also gang up on him and mug him. They beat the poo out of him too!
In the sequels, Dave is now forced to take care of the gangster chipmunks or they'll shoot him with a gun. However, Dave requests they go to school. They go to school because... Uh... Because...Dang it! That's a major hole in this theory!
They go to school for, um... Mass murder! Yeah! And they see some hot chipmunk chicks. So they do bad things to them! The gangster chipmunks are now pimps! That is the only reason the chipettes stay with the hoodlums!
I haven't watched the third one but it was probably, secretly
