Dude: Jorge Garcia, Ian Somerhalder and Conan O’Brien chilling at the Warner Bros. Comic-Con party (Copyright 2011 Warner Bros. Entertainment)

Going to a celebrity party at Comic-Con can be a bit like a fever dream. Wander to the bar to order a drink and on the way, you may run into Aziz Ansari, a former “Lost” cast member, “Cowboys & Aliens” director Jon Favreau or former “Dancing With the Stars” contender Chelsea Kane.

Honestly, just look at the photo above — taken at the Warner Bros. Comic-Con party held Friday night at the Hard Rock Hotel — for further evidence of what I mean. Hurley (Jorge Garcia), Boone (Ian Somerhalder) and Conan O’Brien in the same photo? Even Garcia looks sort of stunned by the whole thing.

As I attempted to navigate my way through the sea of splashy parties, and the abundance of passed hors d’ouevres and random celebrity spottings that entailed, I tried to learn a few things.

(Photos after the jump.)

At the Warner Bros. party, I found out that Michael Emerson starts production on “Person of Interest,” his new CBS mystery/crime series, this week. I also discovered that Garcia is preparing to move to Vancouver, where “Alcatraz,” another J.J. Abrams-produced series that will air mid-season on Fox, will soon begin production as well. Breckin Meyer let me know he’s still upset with himself for not getting that “I Fought the Law” question right during the recent pop culture bar exam I conducted with him and “Franklin & Bash” co-star Mark-Paul Gosselaar.

And, just to keep things fully “Lost”-related, Ian Somerhalder told me he’s heading to Washington later this week to testify on the Hill about the preservation of endangered species.

Then there were all the vital lessons I learned at the Entertainment Weekly party, also held over the weekend at the Hard Rock across from the San Diego Convention Center.

I learned that the cast members of “Community” — many of whom were in attendance, including Joel McHale, Danny Pudi, Donald Glover and Yvette Nicole Brown — genuinely seem to like one another.

I learned from Ansari that we will be seeing plenty of Jean Ralphio (played by Ben Schwartz) on “Parks and Recreation” this season.

I learned that Jon Favreau has some major stamina, as he seemed boundlessly energetic when he entered the party at nearly 1 a.m. after the world premiere of “Cowboys & Aliens.”

I learned that it’s very surreal to see Fred Savage having a conversation a few feet away from Nathan Filion and Mark Pellegrino, the guy who played Jacob on “Lost.”

But mostly, I learned that when it comes to party coverage, sometimes it’s best to shut up and post pictures. So here you go.

Emerson and Garcia, a.k.a. the guys who now run the island, at the Warner Bros. party.
