Take the lyrics to a song and swap out certain words for a spcific set of replacement words then sing it with the altered lyrics. If the replacement word occurs, do the opposite. See how many different and rather interesting things you can get from these.

Start here:
Monday, Money <==> Monkey
Girl <==> Squirrel
Word <==> Bird
Believer <==> Beaver
Momma <==> Llama
Water <==> Walrus
Blue <==> Shrew
Woman <==> Wombat
City <==> Kitty
Hair <==> Bear
Box <==> Fox
Big <==> Pig
Honey <==> Bunny
Paradise <==> Parakeet
Dream <==> Scream
Heaven <==> Kevin
Chapel <==> Cripple
Fuck <==> Duck
Dance <==> Prance
Cloud <==> Clown
Children <==> Chitlin or Chicken


Of course variations will be included such as dream, dreamer, dreaming with scream, screamer, screaming, but only if it's able to match both ways. I've chosen to leave out "love" with something as easy as "dove" since it's so ubiquitous and it just sounds lame. Show everyone what you can come out with below. Feel free to share ones can think up as well and maybe they'll be added.
