So he missed a few years.

So he moved up two weight classes

It's still the same old GSP.

Georges St-Pierre, in his first fight sinceleaving MMA in 2013,submitted Michael Bisping to win the UFC Middleweight Championship on Saturday night at Madison Square Garden in New York City.

Using the rear-naked chokehold, GSP, for lack of better words, choked Bisping to unconsciousness with 4:23 remaining in the third round.

St. Pierre, now 26-2 overall, is tied with Bisping with most victories in UFC history (20). GSP, a former two-time welterweight champion, also extended his fight win streak to 13straight.

Bisping, who GSP praised several times after the fight, falls to 30-8.

"(This) is a dream come true," St-Pierre told the MSG crowd. "Thank you for the support."

"Georges was the better man tonight," Bisping added.

It was quite the night for upsets as the two other championship bouts were won by the underdog. More on that below …
