Video: Spider vs. Penis from Smarter Every Day.

in

Passed along by someone in the the comments section (thanks!):

Yesterday's lecture reminded me of a video from the youtube series "Smarter Every Day". Apparently a bite from the Brazilian wandering spider can cause priapism. The video goes into what causes priapism and has some good info on penis anatomy and erections. Hope it's interesting! (and not too painful to watch)
