e.e. #7: when you get truck drivers to honk the horn

Rewind to childhood. You're going on a field trip with your class. The big yellow school bus is clamoring down the freeway to get to that museum. After having pressed your noses against the windows for some time in search of a big rig, a few of you simultaneously spot one, which is about to pass by real soon...

And, showtime! Many of you four-eyed (but wide-eyed), metal-mouthed (but hugely grinning) kids have now gotten up on your knees on the seats, insomuch as to ensure that the truck driver can clearly see you signaling frantically with flimsy arms, PULL THE HORN!! And most times, he'll happily oblige and make the truck give out a deafening bellow to everyone's delight, as kids scream and hi-five each other for having made this rolling beast come to life.

Aaaand... back to pressing your noses against the windows.

Hey, this still works.
