The Jailhouse

Or it could have been a beverage you (or someone else) shared with the keyboard.

I know from personal experience that keyboards can be rather hostile to beverages after once having accidentally shared part of a cup of very fine coffee with one.

Unfortunately... for some reason, the keyboard did not enjoy the very fine coffee as much as I did and I ended up having to retire it because of its rebellion against such a fine beverage.
