Is it possible to jump on a pogo stick on top of a trampoline?

I imagine you could get pretty high that way! Probably some circus performers can do it. And do ya think they could train bears to do it too? And then, if the bears could be taught, could the bears who understand the finer points of "pogo-leening" then, in turn, teach it to hyenas? Geez, it's pretty amazing the kinds of questions you can ask at Yahoo Answers! (No they are not paying me a commission to ask these never before asked questions).
