Comedy fans are being offered the chance to see two top stand-ups at work this weekend - at a guaranteed heckle-free table.
To raise money for Concern Fast Friends, Tim McGarry and John Donnellan will be providing the laughs at the Limelight on Sunday, October 21.
And four tickets have been put up for auction on eBay, giving punters the chance to bid for a table which guarantees them immunity from on-stage heckling.
A spokeswoman for the comedy night, Stand Up For Concern, said: "The biggest nightmare for anyone going to a stand-up comedy night is that the second you stand up to go to the toilet or the bar, you become fodder for the comedian.
"So what we're doing is giving the fans a chance to have a top table at the front of the house, where you're free form heckling, no matter what you do.
"The comedians have been warned."
Bidding is already under way on eBay and the auction ends tomorrow at 2.30pm.
Tim McGarry is going back to the core of his craft with the headline stand-up set, while John Donnellan is a rising star on the circuit, who hails from Dublin.
The comic represented Ireland at the prestigious 'So You Think You're Funny' competition in Edinburgh last year.
Also on the bill is the 15 Second Film Festival. Tickets are £8.
