Caitlyn Jenner has 'Mrs Brown's' audience in stitches with rude joke

Caitlyn Jenner had the audience of All Round To Mrs Brown’s in stitches as she joked she has “retired” her penis.

The former Olympian was born Bruce but came out as a trans woman in 2015, appearing on the cover of Vanity Fair after a stunning makeover and changing her name to Caitlyn.

A preview clip of the BBC show, obtained by The Sun, shows host Brendan O’Carroll commenting on Jenner having 10 children.

Teasing that 10 is quite the large brood, O’Carroll joked: “Thank God you got rid of it.”

Laughing, Jenner replied: “I didn’t actually get rid of it, I just retired it.”

Jenner’s comment triggered plenty of laughter in the audience.

The 70-year-old, who used to star on US reality TV series Keeping Up With The Kardashians with then wife Kris Jenner, also quipped about her big family being down to her “Olympic swimmers”.

Jenner teased her appearance on the show last month, sharing a photo on Instagram of herself on the set of the comedy alongside O'Carroll in character as Agnes Brown.

In the snap, Jenner is seen reading the fictional newspaper favoured by Mrs Brown, the Northside People, while the matriarch stands over her.

"Had so much fun shooting this funny comedy in Scotland! Mrs. Brown’s Boys!" she wrote.
