PETA's "Save the Whales" billboard (
http://deceiver.com/2009/08/11/peta-...les-billboard/) caused a stir a while back, and now a gym in my city is taking the same advertising approach -- here's one of their signs verbatim:
"In the afternoons
do you get exercise
dodging harpoons?
Synergy Fitness"
funny, but probably not going to gain alot of fatties as customers.
edit: yes, i'm chubby, but i don't think i fit into the "mistaken for a whale category"
