Brendan O'Carroll

Created by and starring a genuine comedic genius, Brendan O'Carroll, Mrs. Brown's Boys is just-about the funniest, cleverest and most seemingly-effortless comedy on British television, deconstructing the classic structures of conventional sitcom and adding great clumps of Rabelaisian filth.

In a way, this defiantly old-fashioned adult panto is TV's brightest emblem of the true spirit of Christmas, seeing as the only reasoned response to watching it is a solemnly uttered "Jesus Christ."

The argument in favour is that it appeals to an audience who have been ignored for too long, namely those overlooked millions who shriek with mirth at the very idea of a man in drag saying rude words and brandishing a vibrator. I can't argue with its popularity, but I can argue that it's a crass, depressing, lazy shriek of badly written garbage.

The only thing that could do more damage to our beloved comedy tradition of cross-dressing is if George Osborne personally demolished a trail of orphanages while dressed as Carmen Miranda.

Anyway, the BBC, in an extraordinary act of cruelty, have foisted not one but two Mrs Brown Christmas specials on us this year (Christmas Eve, 10.15pm, and Boxing Day, 9.30pm, BBC1). And wouldn't you know it, they're atrocious.

I'll give the limelight-hogging O'Carroll one grudging point for at least trying to make them as Christmassy as possible. Mrs B writes a nativity play in which she stars as the Virgin Mary. There's a bit of slapstick business with a Christmas tree, which is practically de rigueur. It's not at all funny, of course, but it's there.

Otherwise it's dismal business as usual: every useless gag is painfully signposted from miles away, before the whole thing degenerates into a horribly cynical puddle of forced, fake, unearned pathos. Tonight's Christmas Eve episode actually ends with Mrs B eulogising her dead dad to the strains of a music box. And this following 25 minutes of crude slapstick and "fecks" in which she's portrayed as a thoroughly unsympathetic ratbag. They'd be better off calling it "Mrs Brown's Schizoid Circus of Doom".

Fundamentally, I'd like to see Brendan O'Carroll introduce the Christmas institution of announcing your retirement from television.

Marmite nature of Mrs Brown

The first time I saw Brendan O'Carroll on stage, I laughed until I cried. Mrs Agnes Brown had finally made her long-awaited Edinburgh debut. That was in 2008 at the Playhouse. I found him funny. Still do.

Mrs Brown Rides Again - live review

The references to gays are horribly unfunny, the show's heavy-handed Oirishness makes me uncomfortable and many of the jokes are so old you could supply the punchlines. But there's an undeniable warmth to this show and it's filled with big laughs because of Brendan O'Carroll's superb clowning.
