Two stories from a good friend of mine in Boston with a bit of IBS...
Summer job delivering mail for USPS door to door old school style. It hit suddenly. Knocked on several doors. No answers. Found a nice shrub. In the process of fertilizing the soil with manmulch, the door opens. USPS uni around the knees. Horrid look on her face. And nothing one can do to stop the torrent.
Also, the Sumner Tunnel in Boston on way home from work after big Thursday night booze, had just finished college and started work, living at home. Friday lunch of burritos....traffic jam. Held for 15 minutes. Shart. And once the shart squeaked through, the torrent came. It was everywhere. Legs, up the shirt, seat, floor, etc... Finally got home, stripped off in the backyard, and his mother used the garden hose.
Both stories verified by other parties (his mother and his roomate)!
