Of course, of the hundreds who make the trip every year, the vast majority never advance beyond the touring circuit of small comedy clubs. Some, if they are really lucky, might land a Radio 4 show, or a TV slot, while a lucky few make the dizzying heights of an arena tour. All, however, have one thing in common: the night they died on stage.
Tiffany Stevenson hopes that she will be the stand-up everyone notices this Fringe - her new show, Uncomfortably Numb, runs at the Underbelly throughout August – but she candidly admits, she too has had the odd stinker. Recalling her worst gig ever, she says, “As comics, we know there is always the possibility of a bad gig hiding round the corner, like a chugger on commission.
“A perennial favourite is a well know agricultural college in the south of England. It has been run by every promoter at some point and still no-one can make it a decent gig.
“You know a gig will be horrific when the student entertainments manager tells you: ‘They love racist and sexist stuff here.’ So, with a leaden heart and fear of not being paid, I got on stage and told jokes about ageing, yummy mummies and my distrust of inherited wealth – to an audience of predominantly rich fifth-generation landowners.
“Eventually I got heckled by two naked rugby players who got on the stage. One grabbed my hand and kissed it. I heard the words, ‘Great, now I have an STD,’ come from a strange disembodied strangled voice – mine. This got more laughs than any of my set.
“I left in tears and with a head full of questions such as ‘Why didn’t they love me when I did all my best racist/sexist material?’ Like all great questions, no-one really knows the answer.”
An experience Stevenson will be hoping not to repeat in Edinburgh.
