From now on, whenever you pass a bus or a limousine with dark windows, start smiling and waving as if you recognize someone in there. Approach the car for a split second as if you were going to talk to them.
If it's someone who's never been in a limo before (e.g. bunch of teenage girls on the way to a wedding), they will probably temporarily forget that you can't see them and get freaked out. It's fun to imagine the possible scene inside even if you don't know the actual outcome.
Whenever you pass a bus that has tinted windows, stare at the (imaginary) people inside the bus, as if you were critiquing their clothes or hairstyle. Again, the fact that the windows are tinted shouldn't matter; the effect, if enough people in the city do this, will be to negate the feeling of coziness and security tinted windows offer.-- phundug, Oct 24 2005 The canonical "let's all" idea.-- bristolz, Oct 24 2005 Aw, c'mon, your earlier annotation was much better.-- DrCurry, Oct 24 2005 But too ambiguous.-- bristolz, Oct 24 2005 But now inaccurate. The nearest this comes to a "let's all," rather than straight instructions for a practical joke, is the reference to "if enough people in the city do this."-- DrCurry, Oct 24 2005 Nah. It's accurate. Read the help file ;-)-- bristolz, Oct 24 2005 I dunno. I think we're reading the "you" differently. (You seem to be thinking "you all," where as I'm thinking "someone following this idea.")
Unless you're indicating it's not especially original.-- DrCurry, Oct 24 2005 The title could use a bit of work.-- Texticle, Oct 24 2005 suggestion?-- po, Oct 24 2005 "Freak Teenage Girls Out"-- DrCurry, Oct 24 2005 The only concern I have is that if I'm unable to make eye contact then it wouldn't freak them out... they would just see a weirdo staring blankly into a random corner on the car ... or at someone's knee. So kind of the same as if the windows were not tinted ... ;-)-- ixnaum, Oct 25 2005 You'd be better off pointing and laughing. Someone in there might be doing something dodgy... then they suddenly think you can see them doing it...-- JoeyJoJoShabadoo, Oct 25 2005 You could always take a few snapshots.-- skinflaps, Oct 25 2005 random, halfbakery
