The myriad characters this week include Tess Daly and Vernon Kay, who pick up an unexpected holiday hitch-hiker; Jonathan Ross, who delivers a great speech; and Fiona Bruce, who is up to her old tricks again on Antiques Roadshow.

Nick Knowles also makes an appearance at the local hardware store and Lorraine Kelly debuts in "Bad Jobs For Celebrities".

The Top Gear cast are put through their paces and Gok Wan, Boris Johnson, Amanda Holden, Amy Winehouse and Cheryl Cole all come in for a good ribbing in this fast-moving sketch show.
