Japanese competitive eating champion Takeru Kobayashi faces off against a formidable nemesis in a cheeky new YouTube viral video that pits man versus hamster in a dramatic hot dog eating showdown.

They’re formidable foes, perhaps all the more so because their small size belie their mega appetites: one boasts a bottomless stomach, the other ever-expandable cheeks.

While Kobayashi has to resort to his dunk, dip and stuff method (dunking hot dogs in water before eating), “Tiny Hamster” tucks his date, grape and carrot hot dogs back with nimble ease.
