At a zoo I used to work at, the porpoises were, ahem, a bit randy. There was a glass enclosure for all to see
The admin heard that feeding them a seagull would tamper their friskiness.
So, the keeper grabbed a seagull and headed out to the porpoise area. Taking a short-cut and crossing thru the lion's den. (Lions had just been fed and were dozing).
As the keeper approached the porpoise enclosure, the FBI pounced on the keeper and took him away in handcuffs.
Why: Because he crossed a staid lion with a gull for immoral porpoises.
