That's always been a classic.
The first couple of times I tried it, it didn't work very well. I was trying to leave in the morning, and I tripped over the can, and I was all, "Who the fuck put a can of tomatoes in front of the door?" And I kicked it out of the way and left without my umbrella.
Then I realized I wasn't going deep enough. You have to open the can of tomatoes and put the open top on the floor. You have to do it fast or it spills.
The next morning, I tripped over the can and knocked it over. And now there was slippery tomatoes all over my floor in front of my door. So of course I slipped in it and fell down, hurting my elbow and head more than I wanted to at that time of the morning.
So at this point, I decided that I could just work from home. After I cleaned up the upside down tomatoes.
The moral of the story is that, no, I didn't remember the umbrella at all. But! I no longer needed it.
