In Episode 4, Beyond the Alley of the Dolls, having Max use the psychic ventriloquism power on the jukebox in Stinky's Diner will have Max sing "I remember my childhood in Brighton..." before Sam stops him from singing any more of the song.

This is the opening lyric to the song "King of the Creatures" sung by the character Conroy Bumpus in LucasArts' earlier title Sam & Max: Hit the Road.
