In the episode the Jerusalem duality from the series the big bang theory sheldon sings aye aye aye aye hava nagila they'll come they'll settle and I'll win the prize does anyone know the song?

It's amazing isn't it!

Basically, Hava Nagila is a Jewish folk song, which Sheldon modified to say he'll "win the [nobel peace] prize".

Good answer but the song is not a modified vesion of "Hava Nagila", It's actually a Mexican (?) song called Cielito Lindo, with the lyrics changed to say he'll "win the prize"
