Just when you thought it was safe to go back to Boston, Mullen has tricked out local landmarks like the Hatch Shell (above) and Weeks Bridge to advertise the Sharks + Rays exhibit at the New England Aquarium. Fins are prominently featured in an ad with the city’s famed Swan Boats and another based on Make Way for Ducklings. (See those, and others, after the jump.) Mullen says a street team of “lifeguards” will swim—I mean, swarm—downtown, directing visitors to the aquarium. I’d volunteer to take part and write about the experience, but I don’t look so hot in a Baywatch suit these days. UPDATE: There’s also this viral video of a shark chasing a tourist boat.
