My sister is far too serious to play pranks on any of our neighbors, so I had to engage in that tomfoolery by myself.

My mother frowns on all types of tomfoolery, from the making of funny faces to the calling of silly names.

People who do not take themselves or anyone else seriously are most likely to engage in ridiculous tomfoolery like putting clear tape over a doorway.

My favorite type of tomfoolery is the kind that makes everyone around me laugh, even if I look silly or foolish.

A clown’s entire act is based on tomfoolery and silliness, such as smashing pies in people’s faces and laughing in an overly ridiculous manner.
