McPhee's Grimoire of Hilarious Object Summoning

The great wizard McPhee was known throughout the Kingdom as the master of magical pranks, japes, and arcane tomfoolery, until his death at the hands (and torches) of a mob of angry peasants. (Apparently, his claim that his new Exploding Crops spell would be a "laff-riot" was only half right.) With the secret knowledge contained in this tome, you're sure to be the life of the party. (Lampshade not included.)
