Indian Man and Cow

Alright, listen up, buttercup. This joke is playing on stereotypes about Indian people and cows. It's saying an Indian man ate a cow because he wanted to get fat. I know what you're thinking. You're sitting there with your mouth open like a carp. It's funny because it breaks a cultural taboo and makes a silly association between eating a cow and getting fat. Now go back to drooling on your shirt.
