Lyrics
Rosita's Red Rhumba: ''Cha-ching, cha-ching, cha-chingaree Money, oh money, how I love thee Cha-ching, cha-chong, cha-changaroo From pennies to dollars, any amount'll do Cha-ching, cha-ching, it's no contest There's only one thing that I love the best From every sight I've ever seen To the sweetest sound I've heard I'd gladly give up everything for all the money that I've earned Cha-ching, cha-ching, cha-chingaree There's nothing on Earth like the feeling of greed! There's nothing on Earth like the feeling of greed!''

Go Grover!: Please don't do that again.
