Guns N' Roses guitarist Ron 'Bumblefoot' Thal was in a serious auto wreck on Tuesday (May 31) but walked away unscathed -- mostly.

The guitarist, who joined Guns N' Roses in 2006, tweeted about the experience in near-real time, first revealing the extent of the crash, then making light of it while reassuring fans, "O please, I'm in GNf'nR - this is all like a walk in the park..."

Thal also used Twitter to thank Toyota for the "functional seat belt, air bags & crumple zone, you saved my skull..." If a picture is still worth a thousand words, click here to check out the image Thal attached to that 140-character tweet. Yeah -- it's kinda a big deal.
