The Barn

A farmer walked into his barn and saw that his brown chicken was acting very strangely. Apparently, the farmer was milking the brown cow earlier that day, and had left his stool near the cow. The chicken had hopped up on the stool and was standing behind the cow. It appeared as if the chicken were thrusting into the cow. It could've been a scene from a nature show or something like it -- perhaps some other show one could download from the internet, if that was your persuasion. The farmer exclaimed:

Brown-chicken-brown-cow

Dunno if this comes across on the internet, or if you have to hear it. Let me know.
