Who Says Government Employees Don't Have Any Fun?

Ok, so the Base has had this banner up at the gate check for about a month now. I shake my head everytime I pass under it. Luckily, today I had the camera with me and I quickly took the picture before any of the gate guards, with large guns, thought I was up to something. So, do you get it? It reads, "Chip Says..." and it's a buffalo. Like Buffalo chip? Anyways, I thought it was pretty funny. I'm just surprised it passed inspection...
