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.
