Exclusive Sullivan & Son Sneak Peek: Big Bang's Kunal Nayyar Returns a Changed Man

The Big Bang Theory's Kunal Nayyar is returning to Sullivan & Son a changed man — or so he thinks.

Nayyar reprises his role as ladies' man and sex addict Neal on Tuesday's episode (10/9c, TBS) who returns to the bar in hopes of making amends for his past indiscretions. However, in this exclusive sneak peek, turning over a new leaf — and keeping a lid on those cheesy pick-up lines — proves easier said than done when a suspicious Steve (Steve Byrne) tries to push Neal back into his dangerous old ways.

PHOTOS: They aren't American?!

As Neal himself says in the clip, "Mothers, hide your daughters! Daughters, hide your mothers!" So which side of Neal will come out on top — get it? — in this epic Dr. Jekyll and Mr. Hyde-esque battle? Check out the exclusive video to find out:
