Question: Why is Dave so grumpy about the chipmunks being so needy to sing in front of Ian? THE GAMER NEXT DOOR
Answer: He knew that if he impressed Ian, he and the Chipmunks would become rich and famous. When they froze, he looked like a lunatic who thought animals could talk, making him appear foolish in front of a man who already had little respect for him.
