Music from 'The Hunted' (Season 2 Episode 5 or 9)

This episode, "The Hunted", shows up as season 2 episode 5 in IMDB, but as episode 9 in season 2 in NetFlix.

At the end of the episode, Hawk tries to cheer Caitlin by playing music snippits in response to statements she makes. He begins with the famous phrase from Chopin's Funeral March, and also plays snippets of Popeye the Sailor, and The Lone Ranger, but it's the 2nd snippet he plays for her, after the Funeral March and before Popeye, that I don't recognize, and I would love to know the "joke."

Can anyone tell me what it is, please?
