Actor-director-writer Ricky Gervais, who has written and directed the British television mockumentary sitcom 'The Office', has banned his audience from having ice in their drinks, reports Mirror.co.uk.

The reason? Well, it's something that disturbs his performance on a microscopic level. The comic reckons the clinking of the cubes in people's glasses interrupts the flow of his stand-up shows.

According to Mirror.co.uk, the ban was in force as Ricky, 61, tested out gags at London's Leicester Square Theatre in preparation for taking his new show on the road. 'The Office' star, who is said to have another Netflix special in the works, drew grumbles from fans with his quirky ban.
