This year's programme kicked off in style as top Scottish stand-ups Bruce Devlin and Des Clarke joined Subway staff at St Enoch Station.
The duo plan to have commuters cackling with delight as they launch the eleventh Glasgow International Comedy Festival thanks to a promotional tie-up with Strathclyde Partnership for Transport (SPT), which runs the Subway.
The duo plan to put a smile on the faces of staff and passengers by providing funny intercom announcements or cracking a joke in exchange for a smile as they issue Subway tickets.
Bruce will also be hosting an underground gig, with four other well-known comics, at St Enoch Subway on Sunday, March 24.
SPT Chairman George Redmond said: "I'm delighted that SPT is to be part of the Comedy Festival, which is easily one of the highlights of Glasgow's cultural calendar. I'm sure that with our Subway stand-up gig at St Enoch and an array of special offers, our passengers will be delighted, too."
Sarah Watson, manager at the Glasgow International Comedy Festival, said: "By going underground we hope to make people laugh on their morning commute and remind them why March is the funniest month of the year in Glasgow.
"Subway users should also look out for special offers for some of our shows."
