Mario Mugan’s Grandad entered the Big Brother house today, as part of the group’s latest shopping task.

In this week’s challenge, housemates must fight all their natural instincts and Ignore the Obvious. For the next three days Big Brother will be sending in a number of distractions to try and get the attention of our housemates.

But in order to pass, the housemates must not react in anyway. Reactions include anything from pointing, laughing, gasping, gawping, flinching, closing eyes, smirking and running away.

So far, as well as sending in a full brass band and a stripping postman, Ben’s friend Dave entered disguised as a toliet attendant. Ben just sauntered past him and didn’t even leave a tip!

Next Big Brother dressed Mario Mugan’s Grandad up as Santa and sent him in to greet the housemates. Looks like Mario managed to hide his reaction well!
