"Sometimes you don't have to change much or be all that creative to make a pretty funny parody song - sometimes you just have to change one word and have a whole new song.
1. Change "Me" to "Smee," and you have yourself a pretty silly pirate song.
ie, "Lean on Smee," "Baby Come to Smee," "I Want You to Want Smee." These work especially well if you can do a good Mr. Smee voice.
2. Change "woman" to "wookie."
"Just Like a Wookie," "My Wookie from Tokyo," etc. You'll have to change a bit more of the lyrics to make it work, but these things practically write themselves.
3. Change "Horses" to "corpses."
"Wild corpses couldn't drag me away." Zombie songs also tend to write themselves."
Gold, ladies and gentlemen. Pure gold.
