Well, he might if he has something to complain about. Like in the episode "The Novelization Correlation (S11.15)".

Sheldon: "I'm going to write mean comments about Wil's show online."

Amy: "Well, you can't criticize something you haven't seen."

Sheldon: "I'm sorry, are you familiar with the Internet?"

Amy: "Well, what if I watch it with you? Maybe I won't like it and we can complain about it together."

Sheldon: "Get your own thing to complain about."

Amy: "Oh, trust me, I've got one. Look, at least if you watch it, maybe you can find more specific things to criticize."

Sheldon: "Oh, that is a good point. Criticisms are more hurtful when they're specific."

Good point! I wonder what Sheldon would say about the big bang theory if he watched it?

"Bazinga!".

"Bazinga Punk!"

He'd think it was a lousy cast, except for that Sheldon character. Why couldn't ALL the characters be like Sheldon?

More Pad Thai, please.

I was thinking more of the times when Sheldon said something like "Of course, with that many Sheldons it would be such a party, we wouldn't get anything done."

Although that's clearly BS, with ANY number of Sheldons it would be more like this:

Would Sheldon post on a message board about a TV show?

Scientist Sheldon – No

Texas Sheldon – No

Fanboy Sheldon – Definitely

Germaphobe Sheldon – No Way

Humorous Sheldon – Yes (as a Troll)

Laidback Sheldon – Maybe…Maybe Not (depending on his mood)

I think it would be fun to have him on this board

Which one?

Think anyone of them would be great to go point-counterpoint with (except Laidback, who probably would end every discussion with "whatev").

Given a choice I'd go with "Humorous"; nothing brightens a day likeat Trolls.

humerous Sheldon, every good board needs some clowns and trolls
