It's some ad for a stripping service. You'd realize it now, but you're too dumb, but this is a double entendre. Stripping, in this case, refers to the act in which one takes off their clothes, but also, to removing paint and paper from walls.
You'd give this number a call, but you're too afraid of the consequences. You just take this time to make fun of this card for using comic sans. What a joke!
