I was just listening to a song with the line "I'm an alka-seltzer and you're a seagull". I'm starting to think that's local knowledge, and I have a global audience here. Does everyone know seagulls can't burp so you can kill 'em by tossing alka-seltzer tablets at one? Their stomachs burst. I never did it, but it was well known where I grew up. Seagulls are everywhere. Do you know you can kill a seagull with alka-seltzer?
