‘Big Bang Theory’ Star Kevin Sussman Is Unrecognizable to Some Fans in Behind-the-Scenes Pic (Photo)

If you’ve ever been gripped by an identity crisis in the face of yet another birthday, take heart — Kevin Sussman just experienced the same thing.

“The Big Bang Theory” star Sussman turned 47 years old on Tuesday, and to commemorate the occasion, his co-star Jim Parsons posted a sweet message to his own Instagram account.

“Happy birthday @kevsussman,” Parsons wrote, along with a photo of the actor on the “Big Bang Theory” set of Apartment 4C, blowing out the candles on a cluster of sweets.

A heartwarming gesture, to be sure, even though it seemed to confuse, momentarily at least, a number of fans who wondered just who it was celebrating his big day.

A number of fans confessed to mistaking Sussman, who plays Stuart Bloom on the CBS sitcom, with “Saturday Night Live” alum Rob Schneider.

“I’m not gonna lie, I honestly thought that was Rob Schneider,” wrote one commenter.

“Rob Schneider?” another asked.

“Anyone else think this was @iamrobschneider?” yet another comment read.

And then there was the fan who ‘fessed up, “I thought this was Nicolas Cage… Lol.”

Oh, well; it could be worse. Last week, Parsons commemorated the birthday of co-star Kaley Cuoco — by spoiling the surprise that awaited her.

Parsons let the cat out of the bag via Instagram — more specifically, a photo of a birthday cake bearing Cuoco’s name posted to his Instagram account.

Parsons commented on the photo, “almost time, @kaleycuoco … shhhhh….”

Which, naturally, tipped off Cuoco to the frosting-coated festivities, as evidenced by a subsequent photo posted by Parsons on his Instagram account. The follow-up photo depicted a very displeased-looking Cuoco, holding up her phone to show the cake photo, with Parsons’ comment.

As if to double-disappoint Cuoco as her big day approached, Parsons captioned the new photo, “oops @kaleycuoco.”
