Yeah, getting hit by a can of beans might smart a bit. But it sounds like a Saturday Night Live skit for people to actually be recommending this as a valid self defense move, and expecting others to take them seriously. I think it must be the same group that recommends racking your pump shotgun and saying "that noise alone will scare them away!" Rrriiiggghhhttt... Maybe they're well meaning individuals giving this advice, but they're also stupider than a stump.
