BBC's Sport Relief delighted viewers with its Line Of Duty spoof where Lee Mack joined the cast as a useless lawyer who ends up implicating his client.
Alongside the usual cast of Vicky McClure, Martin Compston and Adrian Dunbar who play Detective Inspector Kate Fleming ,Detective Sergeant Steve Arnott, and Superintendent Ted Hastings.
He was also joined by Jason Isaacs, who played a man accused of murder, with Lee's character as his lawyer, who does a terrible job of proving his client is innocent.
In fact, he ends up proving he is guilty, much to the fury of his client, corrupt cop DC Taylor.
He then tries to bribe the unit with a measly £5, which does not work.
DC Taylor eventually confesses after a blunder sees his lawyer link his phone to the projector, and he receives a call from "H", who he is trying to prove he doesn't know.
But at the very end, Lee's lawyer character reveals he is H - not realising he is still being recorded.
Viewers loved the sketch and took to Twitter to discuss it.

"Fantastic sketch on #sportrelief ... #h " added another.
