Bruce, I may have been a nanny goat on the outside, but I've always been a billy goat on the inside. The operation has changed all that! Now I'm complete!
I don't understand. Were you lying to me all the time you said you were attracted to me?
Of course not, silly! I'm gay!
So you had a goat sex-change operation so you could be gay with your heterosexual cow/human hybrid boyfriend.
Pretty much! Want to take the new parts for a test drive?
