Alvin and the Chipmunks
One day, he met three talking chipmunks named Alvin, Simon, and Theodore. Initially throwing them out, he lets them in and becomes their songwriter. However, caring for them becomes tough, so to make it up to him, they go to Ian and get a deal. After a while, Dave shows concern for the boys well-being, so Ian turns them against him. After a misunderstanding, they go to live with Ian. Dave misses them while they are gone. He attempts to call Ian to check on them, but is refused. After hearing that they are exhausted, he infiltrates the concert with the help of his ex-girlfriend Claire Wilson. He is ejected, but the Chipmunks see him and turn against Ian. Their overthrow is assisted by He-Who-Must-Not-Be-Aggravated and Brian Robeson. Afterwards, life has returned to normal, with the only change being that He-Who-Must-Not-Be-Aggravated is now living with them.
Alvin and the Chipmunks: The Squeakquel
He is injured in a backstage accident, although the worst is avoided by He-Who-Must-Not-Be-Aggravated's quick thinking Arresto Momemtum. For most of the film, he is in a hospital is Paris. He calls to check on the boys, but Theodore ruins Alvin and Simon's story with a second one, and he yells his catchphrase. Later, he calls again, but Toby answers and reveals the truth, causing Dave to leave the hospital and come home. He arrives at the school just as the Chipmunks and Chipettes are taking a victory lap. Alvin tells him that he told the Chipettes that Dave had said that they could stay with him, to Dave's dismay. He allows them to stay anyway, however. He and Alvin have a "Tired, not tired" fight, until He-Who-Must-Not-Be-Aggravated appears right in front of Alvin, causing Dave to be victorious.
