Big Brother has been around for what feel like forever – and in January there will be new Celebrity Big Brother series. So, to celebrate, we're sharing our favoruite moments from Big Brother history. Most of them involve Nikki Grahame, for obvious reasons.

Nikki Grahame – Best. Contestant. Ever.

…before eating a banana and getting naked

3. "Maybe Nadia's on her period?"
Brian Dowling's shocked face is forever in our memories. Poor Nikki.

4. Pie Jesu never sounded so…just so. 
We can't believe they haven't been on The X Factor yet…
