Well the contest has been going for a while now, and while I'm a little sad that I've only gotten five entries, maybe these will inspire the rest of my readers to come up with their own. Here are the entries:
(Edit: Got a couple more, so I'm throwing them on the end.)
"The second most grabbable butt in the blogosphere." - Alan
"FarmGirl: 1000% of the USRDA of whoop-ass" -Cybrus
"FarmGirl: It's best to stay on her good side. Trust me." - JayG
"I just do what FarmGirl tells me." - JayG
"FarmGirl has a deliciously grabbable ass" - Jennifer
"She'll cut off your nuts and serve them to you." - Loki
"FarmGirl- 98 pounds of of tightly-wound tornado looking for a place to land." - Newbius
"FarmGirl: The world's most heavily-armed twig." - Commenter Ragdragger who did not leave a link.
"As a professional massage therapist it would be unethical of me to comment on FarmGirl's ass." - ChristinaLMT
Hmm. Apparently my posterior is the "famous" one, not me. Anyway, you can vote for your favorite in comments, or if you think you can do better, submit your own outrageous quote via email.
As a side note, the consensus seems to be "don't tweet" so I'll put that idea on the back burner for now, unless a bunch of people speak up in favor of the idea.
