If this is the same one I'm thinking of, I believe it was called "Roaches," a novelty song that was a play on "Rumours," a song from the mid-1980s. It got heavy airplay in Orlando at the time. I don't know who sung (rapped) it.

One of the verses went something like,

"I get up at night, turn on the light, and see the floor show."

Another part went,

"I bet there'll be roaches running around on Judgment Day."

Do you think this might be it? -- Cathy
