Gary Busey Pulls Pants Down, Exposes Penis to Urinate in Public

Gary Busey has that dog in him ... as in, he's pissing in public without a care in the world. The veteran eccentric actor was spotted pulling down his sweatpants and relieving himself Thursday out in Malibu ... urinating on a bush along a wall near a newsstand, and certainly not trying to keep it low key.

Unclear where exactly he's at looks like a lot of some sort. Gary apparently felt a tingle below the belt and had no other choice but to rock a whizz at that instant ... 'cause that's exactly what he did. He even looked around a bit, but there was no shame in his game seriously, just look at that impish smile he's got on here.

The pee pee seen around the world will only add to Gary's many memorable Malibu moments ... the 79 year old is developing a bit of a reputation of late as a bit of a wild man around those parts. Remember ... back in September, Gary was accused of a hit and run. A woman claimed he hit her car in a Malibu parking lot and she chased him down only for Gary to blow her off and drive away.

Gary didn't face any charges for the car incident ... and it will be interesting to see if there are any consequences for this very public bathroom break. Feels like if no one caught him in the act right then and there, he might be fine in this instance. Still ... yeesh . Now, we reached out to his camp over this ...

and they had no comment. We suppose what they say is true when ya gotta go, ya gotta go. Drop 'em and spray ... anywhere/any way..
