Sam Valiant, Private Nose is an episode of The Alvin Show series.
While Theodore tries to find George, Dave expresses his excitement about a new recording he recently finished; after it goes missing, he calls a shady detective named Private Nose to investigate. Sam begins searching for the tape, quickly blaming Alvin and even Dave for stealing it. As he searches he demands that Dave and the boys find clues for his nose. It turns out that Theodore's pet parakeet took the tape, among other things, to make a nest in a hat. In the end, Sam takes Dave's recording and leaves the house wrecked.
- While at Octoberfest in an amusement park (Vergnügungspark in German), The Chipmunks crash into a food stand. As Dave cleans them up, they decide to sing the song in German.

After everyone but Alvin gets a dance partner, Alvin leads one of the conga lines to a bridge outside of town and leaves them. Back with his brothers and the girls, they finish their song.
