Tyler's Anatomy

From the folks who brought you Steven Tyler's pee-pee, we're taking a 180-degree turn to present you with his bony ass in all its horror.

Tyler was back at it again on the beaches of Maui this weekend. The rough ocean waves nearly pulled down the rocker's teeny bikini, but luckily for him -- and you, and us, and everyone -- he was able to pull them up before any real damage was done. Disaster averted ... mostly.
