Man what a great thread bump.
Back in 2010 I went to vegas with a couple bro's. As we are going through security the X-Ray person pulls me aside, I look at the X-Ray image as I walk by and see the outline of a 24oz bottle....I've been iced.
Security guy opens my bag to reveal a 24oz original flavored ICE that my bro's had snuck in bag before we left. They wouldn't let me take the ice there so I had to exit the secure area, chug the ice, then go back through the security line.
