I use an aerosol deodorant so I won't have to touch myself. I know some favor roll-ons, but I oppose anything that involves self-exploration.
Aerosols come in handy when you see a hornet you want to immolate with the flick of the Bic. Aerosol cans explode and that comes in handy, too.
Artful expression is furthered with spray paint. Run alongside trains if you've no crossing in town and I'm confident you'll agree. Aerosol topping can't be beat on pumpkin pie -- I prefer ice cream with mine as well.
I wish condiments were aerosolized, or at least catsup. Spray butter would be nice for evenly coating my toast.
Aerosols make the home smell nicer. Some lubricants are aerosolized. Got a frozen door lock? Spray de-icer.
I hope they never ban aerosols.
