Amy: Guess what I just did for you?
Amy (With overflowing pride and excitement in her voice): I mowed the lawn!!!!
Very long pause.
Tim: Did you catch the clippings?
Amy: Uh, no.
Tim: Well, did you put the plug back in?
Amy: What plug?
Tim: The one you put in when you don't catch the clippings.
Amy (becoming ever-so-less excited): Uh, no. But hey...I mowed the lawn for you!
Equally long pause.
Tim: Yeah. Thanks. Lucky you didn't cut your foot off.
