dressed like a clown?
Tonight marks the 18th day in the big boss house . everyday , the situations and relations in the Bigg Boss house take very interesting turns .

And they have introduced a fun element. We can see Usha Nadkarni and Anil Thatte, two of the most senior housemates relieving their childhood. Usha seems to be recalling how we used to eat cream biscuits as a kid. Of course it looks like a part of a task. But what is this task? Anil is dressed like a

joker

seen humoring Usha and her childish antics.

All the housemates will be dressed up in funny clothes - mostly like a joker or a

child

. Considering, Bigg Boss is all about mind games and survival , it will be interesting to see how this task shapes up and who will win and get immunity .
