Culosfera has the best backsides from the SI Swimsuit Issue. And here is Backside Potential’s category-as-search for The Best Booty Ever. I’m not sure that we have yet found the Michael Jordan of backsides. If you have any nominees, feel free to send them to giveracheltherock [at] gmail.com. I can assure you it’s not Lucia Dvorska, but that doesn’t mean she’s not worth checking out.

Also worth checking out, USC Song Girl Linsey Grubb. Related: Uncoached has pics of Danica Patrick from the SI Swimsuit Issue. Guess you have to be in pretty good shape to be a race car driver.

You probably have to be in good shape to be a boxer too. But it won’t matter if you’ve got fake boobs.

COED Magazine has boyshort-covered backsides galore. I like boyshorts almost as much as short flirty skirts.

And Tasty Booze has convinced me to watch American Idol to see Casey Carlson.

Finally, The World of Isaac has the anti-backside.
