I Always Felt Bad For Wiley Coyote

I once saw a cartoon where Wiley is chasing the roadrunner and he runs into a pipe. The pipe, and Wiley get smaller and smaller until when he runs out his is tiny. He ends up standing beside the roadrunners feet and holds up a sign that says "You've always wanted to see me catch him." And he turns the sign around and the back says "now what do I do."
