April Fool’s Day is supposed to be a knee-slapping riot of merriment, but it requires discretion from the prankster in question.
Debilitating or disfiguring the merry victim seems extreme. The calendar does not absolve the joker of responsible behavior, at least mostly. To some degree. As long as it’s funny.
But a holiday that promotes Silliness should be encouraged. That’s the Rhino Version. We see enough sour faces in the average week. That same face covered with cream pie would promote a guffaw reaction from everyone (except for the pie guy).
