You Just Lettuce Happen
(My mom is in the kitchen eating a salad she just made and I am sitting at the counter a few feet away. My brother walks in just as my mom tilts the bowl, stabs a piece of lettuce, and spills the salad all over the floor, startling everyone with the clatter of the fork.)
Brother: “What happened?!”
Mom: “I tossed my salad!” *proceeds to crack up*
