Michael Phelps, undaunted by the startling lack of humidity in the desert, continues to make the most of his pool-found fame with an extended stay that last night saw him at Tao inside The Venetian. Also hanging out was Meagan Good of Roll Bounce, Stomp the Yard, The Love Guru and Saw V. Hey, uh, Michael Phelps? Try not to take any of her career advice to heart if you were asking her about getting into acting.

Also at Tao were The Late Late Show host Craig Ferguson and poker pros Phil Hellmuth and David Williams.

Earlier, Phelps was at Simon inside Palms Place, along with Olympians Eric Vendt, Rich Lambourne and Stacy Sykora for the Skeletal Metal launch party. UFC light heavyweight champion Forrest Griffin was also there, saying he could’ve used the metal plates the jewelry is fashioned from to heal a broken arm when he was younger. Oh, you know those MMA guys — they’ll never stop talking about their hilarious broken bones.

This is from his first trip, but you wouldn’t be surprised if he walked around shirtless in October, would you?

Inhuman cyborg sent from the future to destroy modern swimming records Michael Phelps was at Prive inside Planet Hollywood Resort with an unidentified brunette and five friends last night, hitting up Money for Nothing featuring Mos Def just after midnight. Phelps kicked it at Table 69 before heading out to the regular VIP area and ordering two magnums of Perrier-Jouet Rose. Phelps was getting close with the brunette through the night, and they took off around 2 a.m. For lessons. Private swimming lessons. We’re sure that’s all it was. What? You aren’t going to learn how to kick-flip on your own.

Clearly, Micheal Phelps is sick of all that water, because he was back in the desert this weekend, soaking in all our sweet, sweet moisture-free air.

The Olympian returned to the Palms, scene of his butt-grabbing glory in September, where he hit up Moon Friday from midnight until around 3 a.m.

On Sunday night, Phelps was over at Wynn Las Vegas’ Tryst, which is at least lagoon-side, where he hung out with friends.

Newly emancipated Holly Madison was over at Lavo inside Palazzo Sunday night.

One more bit of Michael Phelps-related news: The swimmer got himself a custom airbrush job at Sunset Tan inside Palms Place Friday night prior to his dinner at N9NE Steakhouse. Look, the man spends most of his time soaking in a puddle of chlorine indoors. It’s a wonder he doesn’t look like Gollum. Included in his gang of 44 for dinner was Sunset Tan’s Director of Mobile Operations, Amber Peterson.

Each of these bunnies are worth approximately 2.66 gold medals.

Half-man, half-dolphin Michael Phelps continued his “I’m the most perfect example of athletic excellence of all time” world tour with a stop at the Palms’ Playboy Club last night, where he came in with a group of 20 around 11:45 p.m. and took over two tables before leaving around 1:45 a.m.

Phelps wasn’t drinking, but according to one report, he did end up getting his flippers on the go-go dancers.

After the night was over, Phelps descended to the Palms pool where he beat Aquaman, Prince Namor the Sub-Mariner and Sonny Crockett’s cigarette boat in the 400-meter individual medley.
