We had a coworker that was in the dumper every day at the same time. One day we rigged a smoke bomb with some wire and a model rocket ignitor so we could light it off remotely. We patiently waited for him to get settled and just after first grunt, we lit it off and slid a large box in front of the door. Needless to say he never used the toilet at work again.
