Limousine
If you see a limousine, or indeed any very expensive car, shout "Hi Dad!" at it, implying that your father is the very wealthy person being driven in the limo.

If you're in the company of someone who uses the "Hi Dad!" line, retort with "I didn't know your dad was my dad's driver!"

Assuming, of course, that you don't go to a school where being the offspring of gypnak pikey dolescum is considered fashionable.
