Every November the BBC airs the Children in Need telethon where the year's biggest stars join forces to raise money for various children's charities across the UK. Naturally Doctor Who made an appearance to encourage his fans to open their wallets for the children and bid on the chance to own a piece of his clothing.

Find out why his "infinity tweed" jacket and "hyper pants" are named as such in the below skit aired during the British broadcast. You can see all the items up for auction on the Children in Need eBay page.

Get a sneak peek at the Narnia-inspired Doctor Who Christmas Special "The Doctor, the Widow, and the Wardrobe" after the break.
