your lack of generalization makes me want to rollerskate

Figure 1 (submitted for your approval)

While teaching my daughter the art of coasting on a pedal-less bike, I noticed the following sign screwed onto multiple locations around the tennis courts
(figure 1).

The first couple thoughts I had:

• Well, heck! It doesn't say anything about rollerskating, so I should be fine to bust-a-move on these fine courts with rollerskates.
• Hmm...It doesn't mention unicycles. Too bad I don't own a unicycle. Oh wow! We do have a couple tricycles around, and it fails to explicitly exclude those, as well. Just not allowed to ride something with 2 wheels...but WAIT that's not entirely correct.

I continued helping my daughter -- more through encouragement since she was picking up the coasting so darn well -- and after awhile I had formed a list of things you weren't explicitly disallowed to do on these tennis courts.

• Scooting on scooters
• Ripping on RipStiks (questionable)
• Motorcycling
• Roller-sneakering
• Pogo-jumping
• Go-carting
• Bumping bumper-cars
• Horseback riding
• Dog sledding
• Cross-country skiing
• Pogo-jumping
• Oh, have I mentioned Pogo-jumping yet? No? Pogo-jumping. A massive city-wide pogo-jumping contest....not explicitly excluded, is it?
• (verb)-ing (mad lib style)

So, in response to your sign of finite splendor, I declare your lack of generalization makes me want to ________________ (verb)
