John Mayer seems to have picked up more than a few bad habits from his ex-girlfriend Jessica Simpson. Or maybe she picked up a few from him. Simpson has received a lot of criticism for her endless prattling and over sharing in recent concerts. Now Mayer seems to feel the need to join her – though at least he’s not talking about his gas. Yet. At a Tuesday night show at the Mercury Lounge in New York City John kept it classy and chatted up the audience about things like his sweat stains.

… “the sweat stains on my shirt predict McCain will win.” The “subversive hipster crowd” (as Mr. Mayer dubbed the audience) booed, and he smirked and continued, “He’s the juice box fortune heir, right? This is the worst segue into ‘Waiting on the World to Change’ ever.”

In between material both old and new —and a quick few bars of something that resembled Zeppelin—Mr. Mayer mused on everything from recently turning 30 to the inability of people to connect in the digital age. “I know shit will end up on YouTube, but I gotta work it out somehow. That’s the problem with people today. Everyone sits in dark rooms and sends each other links, but it’s a connectedness without really being connected.”

The crowd, undaunted by Mr. Mayer’s philosophizing, shouted jibes like “Nice mustache!” (“Oh, do I have a mustache?” he quipped back) and the singer/songwriter rambled on. “I’ve been doing a lot of thinking lately, which is different from the wondering you do when you’re drunk and in a club.” Here he paused to demonstrate his club dancing abilities. “When you’re drunk, you think you’re thinking, but really you’re just making these intense plans about how you can’t wait to get home and organize your Apple TV and songs.”

Deep thoughts brought to you by John Mayer. Turns out they’re not so deep and rather commercial. Would have expected that? John also checked his BlackBerry and complained that no one ever calls him. According to the Observer, women hit on Mayer all night, and were constantly walking up to him and handing him notes. Then I’m guessing swinging their hips as they walked away. I’m sorry, were you asking him to give you an assortment of STDs? Because I’m pretty sure that’s what’ll happen.

John seems to know he’s fading fast, and it’s like he’s desperately trying to grab on to the last little bit of fame and interest he can. He needs to date another lonely sitcom star fast, or we’re all gonna forget his name.

Here are some classic Mayer concert sex faces for you. Can you imagine how that must look when you’re near him at an intimate show and he’s talking about sweat? John is shown performin in Irvine, CA on July 27th. Photographer: Aaron D. Settipane. Images thanks to WENN.
