Cover art for Big Lizard lyrics by Dead Milkmen, The

This sounds almost like a protest song...

"I ran downstairs to find an army man He said 'We gotta blow up those things we don't understand!'"

The government and other groups act violently because of their ignorance. The big lizard could represent just about anything that the public would go in a panic about, like when black people were protesting for their civil rights. Did the police stop to think of what they were doing? Hell naw dawg, they hosed the protestors down and sprayed the crap out of them with tear gas. They didn't even bother trying to comprehend other's pains. It could also relate to specific individuals, like people who stick out and are hassled because of it (the stereotypical jock vs. nerds thing.)

The Dead Milkmen can right something really catchy and funny but they can be smart. Like, "Surfin Cow"? That song is the truest, best song ever written and has more emotion than national anthems.
