BB3 ones made me laugh, when a few of them were sleeping outside in the garden and they wake up to the sound of two security guardes chasing someone that just made his way through the fence, how the hell did he get through??
When BB kept calling the wrong person into the DR to give the headache tablets.
And when Alex said he got a headache from straining too much on the toilet and then you could hear several people laughing behind the camera.... and after a few second the woman says "Are you Okay?" trying not to laugh.
Also in BB2, someone got into the house too, didnt teh person just open the door and randomly walk in
