"They were ugly, they were mean
Biggest heads I ever seen
They made everybody scream and shout"
"They got slimy lizard skin
And an evil lookin' grin
And they sure could use some manicures"
"They got hands all covered with fungus
They got eyes like some kinda bug
I sure hope they don't come in here
I just shampooed the rug"
"Weird" Al Yankovic, Slime Creatures From Outer Space
