UDF 

A poorly run company that attempts to be cool by using the same tired old puns in their advertising campaigns. Also a terrible choice for employment as all employees are treated like thieves and morons. Also known as United Dairy Farmers.

I worked at UDF until I realised everyone in charge is a dipshit.
