John Mayer has a message for the celebrity gossip world - particularly websites that think they're all that: You can't hang with the best in the biz.

"Snarky gossip bloggers, take heed," Mayer writes on his blog, "You will never have a better knack for cutting people down than Don Rickles does."

In reference to the legendary comc who insults everyone, including members of his audiences, Mayer continues, "You owe much of your success – both pecuniary and otherwise – to the groundwork laid by [Don Rickles]."

Legendary comedian Don Rickles and his #1 fan.

After watching Rickles, 82, perform at Connecticut's Foxwoods Casino, Mayer says, "He made Perez Hilton look like a sycophant. Nobody - and I mean nobody - has what it takes to point out a morbidly obese man in the front row and call him out on it in song" – noting that the man himself laughed hysterically at the bit.

The lesson learned, says the singer-songwriter: "If you're going to make someone laugh at the absurd, tell some truth with it; if you're going to make someone cry, give them a silver lining to look to; and if you're going to insult someone, as the legendary Don Rickles has for the last 55 years, end it with a wink and a smile."

That's good advice. We'll keep those tips in mind, John. Do you own stock in Don Rickles or something? Go write some lame songs, you douchebag. ;-) :-)
