‘Great disservice to me!’ Jack Whitehall, 32, has expressed frustration at his father Michael’s constant jokes about the size of his manhood during their joint interview on The Sunday Project

Discussing the fourth season of Jack Whitehall: Travels with My Father, host Tommy Little asked: ‘It’s a family show for you guys, but were you surprised the amount of time your father brings up the size of your manhood?’

Jack responded: ‘Yes, I am. I remain surprised, and it has become his favourite recurring joke, and there is no environment, no audience, that he will not try and talk about that in front of.

‘He is doing me a great disservice, and it’s all lies and fabrication and him having a dig.’

Michael bewilderingly replied: ‘I think you’re being very unfair. I’m just being honest!’

‘I’m a bit of a wine buff. It’s quite a call for me to actually drink Australian wine, but given I’m prepared to go that far, why would I drink it out of the bag or a goon bag? Absolutely gross, no, no, no!’ he added.

An amused Tommy replied: ‘I’m hoping they told you the beauty of the goon bag is that it serves two purposes.

‘You can drink it, and when you’re done, you can blow it up, and it doubles as a pillow!’
