This episode re-joins the action in the CBB4 house to hear George Galloway utter those eternal words to Rula Lenska, 'Would you like me to be the cat?'
In BB3, the action builds to a shock twist: the house is split into rich and poor sections. This series kicked off the careers of Alison Hammond, Kate Lawler and the late Jade Goody.
From Ivana Trump entering the house to Alex Reid destroying a snowman at the command of a persuasive talking tree - it could only be Celebrity Big Brother 7 - day seven.
Relive one of the simplest, yet most entertaining tasks in Big Brother history. It's BB6 and the housemates are challenged to see who can stay in a carboard box for the longest.
The final episode in our countdown of Big Brother's best episodes is from BB2. Romance unfolds between Helen and Paul. Plus, Helen tells us how much she likes blinking.
