Masuda Kousuke Gekijou Gag Manga Biyori 2 EP12 - Love E

A single man buys a robot girlfriend for himself, but, unfortunately for him, it turns out the product wasn't like what he expected – resembling a trash can on wheels instead of a real gynoid. The robot then proceeds to help him get a real girlfriend, scaring random bystanders and causing pretty severe damage to his physical health in the process.
