I reckon Ben would be more okay than most if he was institutionalized for the rest of his life.
So, is him wearing his pyjamas a part of his three point plan?
1. Wear pyjamas (or bunny ears etc)
2. Do the washing up (lots of people get nominated for not doing any housework.)
#. Listen.
It is not a bad strategy to avoid nominations, but during the listening bit you must be both compassionate and funny. Ben can be.
And I would add
4. Do pranks or something to get airtime. BB wont give you job interviews all season - although, they did leave it open for him to return to that. Cringe. Imagine seeing Ben doing that now. I want him to be good, to be a genuine character, but he is just coasting.
