Improv comedy

After college, he joined an improv group with Mike McShane. Both Proops and McShane impressed producers Dan Patterson and Mark Leveson, who put them on their show, Whose Line Is It Anyway?. He frequently instigated jokes concerning various idiosyncrasies and differences between British English and American English, and would frequently banter with Clive Anderson on these matters (among others). He lived in London for four years when he was doing the show and lists McShane, Richard Vranch^[6] and Colin Mochrie among his best friends. After the show ended, he was recalled for the American version and has been a frequent "fourth contestant". Through 2020, he has appeared in 74 U.S. Whose Line episodes, more than any other non-regular cast member.

Proops also appeared in every episode of the short-lived Drew Carey's Green Screen Show, where the performers would play improv games (some of which were taken from the show's main influence Whose Line Is It Anyway?) in front of a massive green screen.^[7] Later, animators would draw on the background and other props. In April 2011, Drew Carey's Improv-A-Ganza premiered on GSN featuring Proops along with other frequent guests from Whose Line is it Anyway? In July 2012, Proops appeared in ABC's improvisation show, Trust Us with Your Life.^[8]

In November 2011, Proops did a week on Royal Caribbean's Freedom of the Seas with the Lewis Black Comedy Cruise Tour. He performed the entire week of stand-up with other artists, which included a live, one-hour podcast in front of his entire audience.^[9]

Film and television

Proops has performed his stand-up act across Britain, mainland Europe, Australia and New Zealand. His other credits include hosting Space Cadets, a mid-1990s science-fiction comedy game show on Channel 4 in the UK, which also featured Craig Charles (Dave Lister from Red Dwarf) and Bill Bailey, and appearances on BBC2's Mock the Week. He appeared as a panelist on the 2000 revival of To Tell the Truth. Proops has also hosted game shows, including VS. in 1999,^[10] Rendez-View in 2001,^[11][12] and Head Games, a Science Channel game show which ran for one season in 2009.^[13] Proops also competed on the November 8th, 1984 episode of Jeopardy!, losing to eventual five day champion John Genova. He would later record video clues for two Jeopardy! episodes in 2000 & 2001.^[14]

In addition to his stand-up and improv acts, Proops has done voice work in various films and TV shows, including Tim Burton's The Nightmare Before Christmas, and the miniseries Stripperella with Pamela Anderson. Proops provided the voice of Bob in the US version of the TV series Bob the Builder for the five seasons of Project Build It. He has also featured in 2003 film Brother Bear as the voice of one of the Love Bears and provided the voice as Cryptograf in 2006 film Asterix and the Vikings.

Before Smartest Man, Proops hosted a podcast called The Greg Proops Experiment.^[17]

In 2010, Proops hosted Odd News on yahoo!.com for several years. It was a weekly program where he told weird and funny stories from around the world. Sadly, they all appear to have been removed from yahoo! completely, even direct links from other sites bring you to a page stating that the page you're looking for no longer exists. The series seems to have continued in text format and on Twitter for several years after Proops was no longer a part of it.^[18][19][20]

From 1995 to 1996, Proops presented Bits from Last Week's Radio on BBC Radio 1. He did voice work for the BBC Radio 2 series Flight of the Conchords, first broadcast in September 2005. Proops also played the title role in BBC Radio 4's sci-fi comedy series Seymour the Fractal Cat.
