Mike "The Situation" Sorrentino is reportedly getting teased a lot behind bars.

It's only been a week since Mike ‘The Situation’ Sorrentino he turned himself in to begin his sentence at the Otisville Federal Prison to serve, but he's already having a hard time.

The Jersey Shore star is currently an eight-month sentence for tax evasion.

A source told RadarOnline:

“Mike was talking about how his workout routine is far tougher than what the other guys here do,” Federal Prison Consultant Dan Wise told them

“But I am hearing that when he went out into the yard this past weekend to work out with a few of the other guys he didn’t even last ten minutes.

“Mike couldn’t hang at all and puked before laying on the ground to try to catch his breath. Everyone was laughing because he was trying to be this big show off and couldn’t last ten minutes when it came time to show them all what he was made of,” Wise added.

But another source told the entertainment outlet that Sorrentino is the reason for the jibes.

“Nobody inside is really bullying Mike, per say. He is getting teased a lot though because he is so full of himself. He is already being brought back down to size though and he is holding his own. He is not really being rude to anyone and is just kind of like this goofy middle-aged dude who seems to be stuck in the 90’s.”

Well, things could be a lot worse...
