It's a before and after comparison that will make you proud of Kevin Smith.
The 44-year-old Clerks director took to Twitter and posted a 2008 shot of him and his daughter, Harley Quinn, alongside a shot from two weeks ago to show off his 85 pound weight loss.

Smith certainly had extra incentive to drop the pounds after he was kicked off a Southwest Airlines flight for reportedly being overweight in 2010.
At the time he tweeted, "Dear @SouthwestAir I know I'm fat, but was [the] captain really justified in throwing me off a flight for which I was already seated?"
He continued his Twitter rant saying, "So, @SouthwestAir, go f*** yourself. I broke no regulation, offered no 'safety risk' (what, was I gonna roll on a fellow passenger?)"0
When Smith later boarded another flight, he posted a picture of himself in his seat, writing, "Hey @SouthwestAir Look how fat I am on your plane! Quick! Throw me off!"
Southwest responded by offering him a $100 voucher and apologized, but now Smith obviously has the last laugh.
In February, Smith told Men's Health about how he changed his diet, including what he drinks.
"I can't even walk down the drinks aisle at a food store anymore because all of it is just sugar water. There's nothing there that's not sugar water," he told the mag. "I used to be a guy that was like, 'Yeah, I drink juice, man, and juice is natural.' When I stopped drinking sodas and juice and stuff, the pounds just started flying off."
And while he gave up his weight, there is something he isn't giving up -- those long shorts!

In his proud tweet, he wrote, "I shan't wear pants and will never abort the shorts."
