Scene: The character played by Rene Russo goes to the office of the character played by Tim Allen to return his reading glasses that he dropped the night before at her house.

Tim Allen pours a cup of coffee for Ms. Russo at his office, the two then start kissing, and making a mess of the room. The entire time Mr. Allen is holding the cup of "coffee". There are several times when some of the "coffee" spills out, to reveal that it is actually water.

Now that's what I call weak coffee.
