Here are some good sites to check out when deciding which player to pick.

Our latest Pizzazz worksheet gave me the idea to make a post about Swifties, a form of pun inspired by the Tom Swift book series.
As you no doubt remember, our worksheet contained the following three Swifites:

"I hate playing tic-tac-toe," Tom said crossly.
"I wish I were six feet tall," Tom said longingly.
"I just flew in from the coast," Tom explained.

Michael J. was the first student to come up with new Swifties. His two were:

"I wish I weren't so short," Tom said briefly.
"I wish I had some money," Tom said lonesomely.

Let's see how many Swifties we can come up with as a grade. Post your best puns here.
