The Mount Saint Helens classic is where you fill a pipe full of ash and give it to your friend, when they light it with a torch all the ash sucks to their mouth.
A randy drunk-guy song with the same melody as "Yankee Doodle Dandy" depicting Helen Keller riding on a pony into town, putting a feather in her hat and calling it "habawoney".

When a girl is giving a guy a blowjob, the guy puts both of his hands over her ears and pulls her as far onto his cock as possible (this works best with a guy who has a large bush and doesn't manscape). Then she can't hear anything, can't see anything, and essentially cannot speak coherently.
