Some days, things just don't go your way. Tuesday after work I walk to the parking lot...

The rear passenger door of my Honda Fit

You can barely see it, but the in-door speaker is obliterated
The obvious solution to this mystery is not the correct one...

Well, I give up for now, and decide to just get home. I double check my backpack I threw in the passenger seat to make sure I have my coffee cup...

In that moment, I realized I was both stupid and unlucky.
See, I recently moved to Denver, Co and had brought a canned of compressed air up to clean my stuff after visiting New Mexico. Being lazy, I unpacked all the big things, but left that can in the cup holder in the door.
It was in there for a little more than a week, all the while heating in the sun and cooling at night, weakening the aluminum and pissing off the air inside (presumably).

You can't really see it, but the bottom the can is domed outward. It actually looks like it has little tabs etched in to blow out if the pressures get too high... but they failed. The amazing thing is that the main part of the can flew up and broke a handle on the front passenger seat and leaving a little tear in the ceiling material before falling into the seat.
The lesson is: read the warning label, and then do what it says...
