And during one recent episode, the 63-year-old appeared to forget where his mouth was as he attempted to take a sip of his drink, much to the delight of viewers.
Oh and just in case viewers missed the funny moment, Cowell also shared it to his Instagram, writing: “Caption this… #BGT”.
It’s nice to see TV’s harshest judge can still take happily take the p**s out of himself, isn’t it?
Cowell’s 1.8 million followers loved the silly clip, with one person replying: “I just laughed out loud so hard.”
Another said: “I watched this live and was absolutely wetting myself.”
Someone else joked: “I think there's something a bit stronger than water in that glass.”
A fourth person wrote: “Don’t know why but howling.”
While a fifth person made the incredibly accurate comparison: “When you’re trying to find the outlet port in your phone to charge it when it’s dark in your room.”
This isn’t the first time Cowell has had a laugh at his own expense in recent weeks - just last month he cracked a gag about his changing face during an episode of Britain’s Got Talent.
Tom Crosbie appeared on the show, where he made an art piece of the faces of Albert Einstein and judge Bruno Tonioli using Rubik's Cubes, prompting a blown away Cowell asked how he managed it.
Crosbie replied: "Practice, lots of different faces. It turns out you have a really difficult face to make Rubik's Cubes out of."
In response, Cowell quipped: “I will change my face… again.”
Cowell has previously admitted he had ‘gone a bit too far’ with his past treatments and at one point barely even recognised himself in the mirror.
"There was a stage where I might have gone a bit too far. I saw a picture of me from ‘before’ the other day, and didn’t recognise it as me first of all,” he told The Sun last year.
“Eric [Simon’s son] was in hysterics. Enough was enough. There is no filler in my face at all now. Zero.”
He added: “Actually, for me now, a lot of it comes down to healthy eating and drinking tonnes of water.”
Well, if he can manage to find his mouth with a straw that is.
