The Ren and Stimpy Show - Season 3 Episode 4 -

After Stimpy gets out of the shower, he finds that there is not a pair of pants in the house. Ignoring Ren, who tells him that clothes are for humans, and that he doesn't need pants, he tries multiple times to find a pair of pants, without much luck. He is shunned by the outside world because he is nude. He eventually gets lost in the forest, cold, naked, and embarrassed.
