Q: Where must a tennis serve land to be considered in?

A: It must land in the field of play.

The grassy area, marked by the lines.

It must land inside those lines. Inside that box, specifically.

A serve that lands in the gaping maw of the Queen Mother can not be consider in.

I am being serious.

Lower your voice.

We are all impressed by your trick shot ability, and your timing. We all agree that she was snoring rather loudly and disrupting the game.

While you are due a kudos, sir, and a smattering of light applause, you do not deserve any points.

Now please gather the remnants of your shattered racket and resume play. It is your serve.
