Legends of Comedy Improv, Stephen Frost and Ian Coppinger joined Cooper and Luke in studio this morning.
They're bringing their show, Who Are The Improv Allstars Anyway to Vicar Street next month on the 27th October.
Taking to the stage with five other comedians, there are no scripts, no preparation and no rehearsed lines to fall back on. The lads are pretty much the Premier League of Improvisers and have no idea how the night will unfold.
Stephen (best known for his ten year stint on Whose Line Is It Anyway?) and Ian (Co-Founder of the Dublin Comedy Improv) gave a little improv taster ahead of the show
Join Cooper and Luke on 98FM's Big Breakfast
