One of the highlights of this old-fashioned variety hour is the segment where Michael lets himself into a celebrity's house by night (the front door is always conveniently open) and bursts into the bedroom to play pranks on the stunned victim.

Michael would be well advised not to try this game if he ever takes his show to the U.S., since most American celebs sleep with a shotgun over the bedstead and a handgun under the pillow.

Judge Rob Rinder was the guest this time and, though he was characteristically grumpy, he didn't attempt to shoot the intruder. Oddly, he appeared to have a bullet-proof glass balustrade around the bottom of his bed, so perhaps guns give him nightmares.

The best bit of the show is still the game in which Michael borrows a celeb's phone and sends a cheeky message to all their contacts. It gets funnier every time.
