There was also a chicken hay bale.
There was also a hay bale that depicted a man palpating a cow (one way you can check for pregnancy in a cow). I left that one out because it involved a man having his hand up a cow's rear.
The sorority I used to be in also had a hay bale. It was decorated like a smore, but it just didn't photograph well. I also left that one out.
If you live in the Athens area, these hay bales are located on South Milledge Avenue near where South Milledge ends into Whitehall Rd.
