A Case of the Giggles

Momma is presenting a lecture on “Long Horned Beetles" and the whole family wants to attend. Daddy explains to Martin and Sylvia that they'll need to be still, quiet, and attentive during the lecture. Just in case they should be beset by "a case of the giggles," he teaches them a technique to help calm and quiet themselves. But, as it turns out, it is not the children who end up with “a case of the giggles.”
