Could whistle normally as long as I can remember. Tried forever to learn the two finger loud whistles as a kid and never could make a sound but still tried. I still recall when I was around 13 yo reading Goosebumps and randomly did the gesture when suddenly I made the first successfull attempt. I literally turned to the mirror on the side becuase of the surprise and had that Shaq face on Hot Ones. After practicing for a while I discovered that, while you can whistle EXTREMELY loudly this way, you legit hurt your own eardrums the most. Basically kamikaze whistling. I don’t use it that often because of it.
The third way of whsitling is by blowing through your palms which makes that owl-like howl. You can basically do the first part of the song in Once Upon a Time in the West this way.
Also, snapping your fingers in a very “snappy” loud and deep kinda way.
I’ve heard one of the reasons you don’t often see people smiling on old photos is because you had to hold the pose for quite a while. So in order to make it easier (and prolly not look like an idiot) they often went for the most mundane expressions. Not sure if it’s true though. Someone more informed is welcome to enlighten me.
Boiled potatoes, maybe. But I wouldn’t count on the eggs, especially when it can get hot outside.
Petah?
