That's Supposed To Be Three Penises On This Billboard
It's a teaser board erect(heh)ed in Hollywood promoting the third season of "Workaholics." Those men must have some pointy penes.
Workaholics is a Comedy Central show about three recent college grads desperately trying to adjust to adulthood (and erections, apparently).
Sorry, but that's three nipples, like the mutant prostitute in Total Recall had.
Embarrassingly bad artwork.
HBO got it right back in 2010 with this Hung billboard in New Zealand.
