The "Waltz me around again, Willie" limerick song is set to the chorus of "Ceilito Lindo," Gargoyle.
And folks, try to top this one that I got from a small book of dirty limericks by someone called Count Palmiro Vicarion:
My back aches, my penis is sore;
I really can't fuck any more.
I'm covered with sweat
And you haven't come yet,
And, my god! it's a quarter to four!
