A new study out of Oregon State University has found that rams that love to get rammed have a different brain structure than those damn breeder rams. The study was conducted to ensure that those who purchase rams for breeding get a hetero one. Apparently ram breeders are not fans of ram-on-ram action. That's just too much ramming going on.
On another note, the gay rams apparently have the same reaction that gay humans have when they see a female's particulars: "Ewe!"
(Yes. Sorry. I had to go there.)
