The History of Comedy, Shop Well for Less? and Upstart Crow all return, while it's the end of the road for Lethal Weapon . . .
Pick of the day
The History of Comedy, 9.00pm, Sky Arts
If this second run is anywhere near as good as the first, this will be essential viewing.
This time the spotlight falls on a broad range of comedy styles, from teams such as Laurel and Hardy, the Marx Brothers and The Three Stooges, to more clean cut family-friendly comics such as Jerry Seinfeld, Jim Gaffigan and Ellen DeGeneres.
It also takes a closer look at boundary-pushing sexual humour across stage, stand-up, TV and film and innovative animations such as Mickey Mouse, The Simpsons and South Park.
It doesn’t matter if you’re a fan of improv, sitcoms, sketch shows, one-liners, black comedy or physical comedy - if you like to laugh then this is pretty unmissable.

Welcome my lords, ladies and groundlings to the third season of Ben Elton's sitcom starring David Mitchell, based on the life of William Shakespeare.
Will (David Mitchell) is just finishing writing A Midsummer Night’s Dream, a tale of love potions, enchantment and a wood full of fairies.
He’s very pleased with how realistic it is, as he based it on his own experience. But his Burbage (Steve Speirs) and the other actors tell him it lacks a little comedy, like, say, a character with a funny name or a big visual joke.
