Hi, miriam.
The clip was shown on BBLB during the week after Paul was evicted.
It was after the dinner dates had finished, and Paul was sitting on Helen's lap talking to Big Brother (although at the start of the clip you didn't know that Helen was there).
Helen then started to tickle the back of Paul's neck. He stopped talking then giggled and went 'Ahhhhhhhhhhh', leaning to the side to reveal Helen's beaming face behind him.
It's not a very good description (sorry!) and the clip only lasted about 5 seconds, but it was absolutely priceless!!
