Aight, bear with me, but the Roy Walker story is (and keep in mind this should be repeated verbally, complete with appropriate sound effects)
Roy Walker had done a show at the Fringe- quite a few old comics do this, and this was a few years ago now. After Roy Walker's set, the comedian in question, who was in the audience, went for a piss. The gents was one of those where the urinal goes all the way around three of the four walls, so he took his place in the U shaped piss line.

It just so happened that Roy Walker himself was having a piss too. While marvelling at his esteemed urinary colleague, one of the gentlemen at one of the ends of the U let out a short, sharp fart.

The noise from this fart reverberated around the tiled acoustics of the pissy cavern. Sniggering happened.

The man next to the farter, in a moment of exuberance, squeezed out a fart to join in.

An unspoken agreement was signed, and the men in the U embarked on what can only be described as a Mexican fart, while sniggering multiplied itself across the alcohol sodden pissy circuit.

When it was Roy's turn, well, Roy tried his best but could only manage a limp, pathetic Tommy Squeaker of a fart. The sniggering was replaced with one jolly wag proclaiming...

It's good, but it's not the right answer!
