He is a member of The Tenderloins, a comedy troupe also consisting of Sal Vulcano, James Murray, and formerly Joe Gatto.

[4] The Tenderloins began producing comedy sketches together, posting them on YouTube, Myspace, and Metacafe, accumulating millions of views online.

In October 2019, Quinn, along with the other members of The Tenderloins, starred in The Misery Index, which is hosted by Jameela Jamil and is based on Andy Breckman's card game "Shit Happens".

The podcast started in February 2010 with Quinn in the role of the off-mic audio engineer, then shortly after as occasional commentator and ultimately co-host.

[7] The increased popularity of What Say You sparked a friendly competition among the comedians, spurring Joe Gatto and James Murray to release their own Tenderloins podcast without the other two members.

[8] The group explained that it was difficult to coordinate the schedules of all four members outside of work, making it challenging to produce their troupe's official podcast with any regularity.

Quinn was escorted back to the United States by German police, and was bailed out by his Tenderloins troupe members.

[10] Since his time on Impractical Jokers, Quinn has donated $50,000 to the New York City Fire Department, and he occasionally meets with his former coworkers.
