He was even behind a new discovery at the Penn Museum this week.
And he inspired Stephen Colbert to create his own mascot for The Late Show: Trash Slob.
Now, Gritty has inspired something Philadelphians can really get behind: beer.
Broken Goblet Brewing of Bristol has created "NIGHTMARE FUEL," a lightly hopped cream ale with vanilla and "bruised and bloodied oranges" to commemorate Gritty's arrival on the world stage and on social media.
We imagine the name was spelled in all caps because they've mixed the Gritty-induced screams of small children into the brew.
The beer — which features a bruised, semi-teethed monster that looks an awful lot like Gritty — will be released Oct. 13, according to Broken Goblet's Facebook page.
Before the name of the Gritty-inspired brew was officially announced, Broken Goblet asked its fans for suggestions on what it should call its new beer. Responses ranged from "Grit Faced" to "Gettin Gritty With It."
One fan even suggested naming it "No One Likes Him, We Don't Care!" a knock at Gritty's popularity (or lack thereof) and a nod to another of Broken Goblet's sports-inspired brews: "No One Likes Us, We Don't Care."

While Gritty has his fair share of detractors, who would rather sip haterade than anything inspired by this orange, furry jawn, he's also developing a groundswell of support among fans who will undoubtedly raise a NIGHTMARE FUEL to his health.
And we'll drink to that.

If you have nothing to hide, why are you avoiding us, Grit man?
We noted something interesting, though, in the below video, which was posted by WMMR's Preston & Steve Show. In it, Gritty lifts up his shirt and reveals that he's got an outie belly button.
So if the Flyers thought of everything down to Gritty's belly button, there's still one thing about him that doesn't pass the smell test for us: Where's his nose?
