What song does "Bimbo Number Five" parody? (It's a familiar tune, maybe a swing dance-- click link to hear)

I've heard this song before and wondered what it was. What I have a link to here is a parody of the song, but hopefully from the tune alone you can tell me the title. http://www.youtube.com/watch?v=mG2LyY8-H...

Mambo number five by Lou Bega, from the cd A Little Bit of Mambo

Mambo #5 by Lou Vega

Parody of Lou Bega's Mambo #5

It's Mambo Number Five.
