Online t-shirt company Psycho Reindeer have this fantastic monkey brain surgeon t-shirt with which you can proudly display your brain tinkering tendencies.
It’s only $14 and looks kinda funky.
If you do have a monkey by the way, it’s best not to let them do neurosurgery with a screwdriver as the t-shirt suggests.
I always make sure that they’re involved purely in an advisory capacity.

Oh dear, how sickeningly reminiscent of human tucking into monkey brains……..pass on this one, I think.
