Fish4fun,

Something Steve and I got going is to try to get someone to look in the direction that puts the back of his head is toward you. Once he's looking the other way, bump his line with the tip of your pole and watch them go into the "suprise hook set" motion.
We will wait patiently all day long to spring that on each other, being very wary that we both have the same thing in mind. If you ever pull it off on Steve, tell him I told you about it.

Sea Lemon,
It's an oldie but a goodie, but you can put a rubber band around the sprayer trigger at the kitchen sink. That'll get both the wife and the kids.
