Poison Cream

Isaac: “Dad, taste my ice cream.  It’s really good.”
Richard: “Okay.” [tastes ice cream].  “It is good.”
Isaac:  “Aha!  It’s poison ice cream!  Now you will die and I can do whatever I want.”
Richard: [feigns death].
Isaac: [grin changing to frown] “Oh no!  Mom!  [pause]  Um, Mom.  Taste my ice cream!”

Hammer

Richard [refuting all of Isaac’s efforts to deny the tale of his brother Ralph who was eaten by a giant lobster]: “You can’t out-story me.”

Isaac: “I’ll hit you with a hammer.”

Richard [stunned pause]

Isaac: “The End.”
