6mile, ROFL!!!
I like it, that's great...
I was once on a flight where this lady in the row in front who had been yapping on her phone in the boarding lounge (ala "I'm so important, look at me I'm a powerful businesswoman" thing) got up while we were taxiing in to the gate. She had been contradicting the crew all flight and generally being rude so of course I didn' like her much...
I guess the crew hadn't seen her yet and I said "I think you should sit down in case he stops..."
Of course she just made some rude remark and said "I don't need to sit down-" at which the plane braked suddenly coming into the stand and said lady fell really ungracefully back into her seat, dropping her phone, PDA and papers all over the floor, getting loads of sniggers from the other pax who thought she well deserved it!!
You could always use a variation on the old chestnut and say "First one who stands up before we stop has to clean the plane".... should work a treat!!
