Dale Earnhardt Jr. is a funny dude.

Belief in the paranormal, unabashed pickle worship and apparent suffering from jewelry phobia are just a few of the retired NASCAR driver’s interesting quirks. So, it should come as no surprise that Earnhardt likes to sign bathroom stalls.

Reddit user jacoobz recently shared a photo of what appears to be Earnhardt’s signature on a stall at Pocono Raceway. Twitter user Landon Haugh then re-shared the photo, asking Earnhardt if the signature truly was his.

Here’s the photo:

So, what’s the verdict, Dale?

There are two ways to read that comment: Either Earnhardt really is just kind of sure that it’s his autograph, or he’s signed so many bathroom stalls that he’s not sure what’s real and what’s not anymore.

Either way, let’s hope the custodial staff at Pocono never repaints the stall.
