“It’s time for recess,” Tom said playfully.
“I can turn on the lights,” Tom said powerfully.

Tom Swifties are a type of humor from a series of old books.  I have not read the books but I love the odd humor in Tom Swifties.

A Tom Swiftie has Tom saying something in a way that relates humorously to the words that he spoke. Typically the sentences end with Tom said [adverb]. For example… “This coffee needs more sugar,” Tom said bitterly.  This is funny because coffee has a bitter taste, and Tom said this bitterly.

Here are a few more examples I found on Wikipedia with a short explanation I added in parentheses:

• “Pass me the shellfish,” said Tom crabbily. (Crabs have shells.)
• “We just struck oil!” Tom gushed. (Oil gushes from a well.)
• “Get to the back of the ship!” Tom said sternly. (The back of a boat is called the stern.)
• “I forgot what I needed at the store,” Tom said listlessly. (If you make a list, you won’t forget.)

If you create a Tom Swiftie you can send it to me and I will add them to an upcoming post.  Or you can leave a comment with your Tom Swiftie.
