A friendly greeting by hand Or roars across the ocean to land Ripples through a stadium stands Can carry signals to different bands

I am a sign. I start off as a vegetable, but quickly turn into an expert. It's probably a little cliche, but me and the world used to be a staple at beauty pageants. Some people use me before they go away.

I can be cracked, I can be made. I can be told, I can be played. What am I?

While it sounds yummy, it’s probably a top that you don’t want to have, especially if you’re wearing tight-fitting pants or skirt.

I sound like you can take me on a plane I guess you could, but you’d be insane.
