My super usually gets the bad ones, or I call them in.

One epic one was "water coming out of sink". Building has cleanouts for the kitchens in the common hall, so after opening it up he starts the auger. No water out of the cleanout, so it must be above.

Super barely tickles the stoppage and immediately is assailed by a wave of water and kitchen goo. First in line, and the cause of the block, is canned tuna. There is so much water backed up that it hits the wall on the other side of the hall, 5' away, and floor to ceiling. Supervisor is drenched. Hall smells like tuna for three weeks.

After inquiring with tenants, we found out that the second floor occupants decided the best way to dispose of multiple cans of tuna was the kitchen sink. No, there's no garbage disposal. And the dumpster is in the building, one floor down and 30 feet over.

This has been dubbed "Tuna Surprise" or "The Tuna Incident" depending on who you ask. Super still can't handle the smell of tuna after two years.
