i need it

how do i get my hands on a neuron t-shirt like my fave professor's??

not pictured, but it is black with a red silhouette of a (pyramidal) neuron on the front. kinda like this one except prettier:


also, one of my classmates had a similarly nerdy (median sagittal diagram of a) brain t-shirt on during our final exam last week.

jealous.
must make.

would it be creepy of me to ask the prof about borrowing his t-shirt for this? hahahhahah...
