I shit you not, this just happened:

* I take a shower and leave the bathroom door open.

* I get out of the shower.

* The smoke detector outside the bathroom door starts going off.

* I run upstairs to see what's going on.

* The smoke detector turns off.

* I slowly step back downstairs, somewhat confused.

* The smoke detector turns back on.

* I step back upstairs and it turns off again.

* I laugh heartily.
