Line Of Duty and Killing Eve will join forces with Sport Relief next month for hilarious one-off skits.
While AC12 have been hot on the trail of the mysterious H, in a sketch they will take a break from their interrogations to go head-to-head with newcomer DC Taylor and his half-wit solicitor.
Meanwhile for one night only Killing Eve will be re-branded as Killing Steves, as a slew of the appropriately named male stars are victims of a certain blonde female assassin.

In Line Of Duty's special, DI Kate Fleming, DS Steve Arnott and Supt Ted Hastings will be grilling the 'bent copper' DC Taylor, played by Jason Isaacs.
But his attempts to escape prosecution will the thwarted by his half-wit solicitor, who will be played by comedian Lee Mack.
Killing Eve fans will also be treated to one-off skit, as celebrity Steves, including snooker Steve Davis and sports legend Steve Redgrave will be comically killed off by a mysterious assassin.
Fans will have to wait and see who is behind the murders, but given the sketch's name, it's likely that Villanelle won't be far from the drama.

Line Of Duty is currently in the midst of filming its sixth series, which is expected to air later this year, while Killing Eve will return to US screens in April with a UK release date yet to be confirmed.
Sport Relief's bi-annual telethon will air on BBC One on Friday 13th March, and will also feature the conclusion of The Heat Is On challenge.
The epic feat has seen eight celebrities embarking on a 100-mile trek across the Namib desert, including Frankie Bridge, who shared a snap of herself during the trek's final day on Wednesday.

Frankie and the team- Karim Zeroual, Krishnan Guru-Murthy, Louise Minchin, Rob Rinder and Samantha Womack - scrambled across the great desert dunes of Namibia on day three of the challenge and will now take on 13 miles of the skeleton coast.
Ahead of the trek, Frankie said: 'I've never been to the desert before and I don't know what I do and don't need. The enormity of the whole thing is just really starting to kick
