Curval,
Yeah, that is a really smart trick. Unfortunately we are not allowed to smoke in court here. And our legal system is pretty different from the US system. We have no jury for instance. But it would nevertheless be useful if you want to distract the court from what the other guy is trying to get from the witness. Perhaps I could sneak some play-dooh into my nose, and slowly drag it out while the other guy is cross examining.
Sidenote: Speaking of noses. Back in high school I had a friend who always ate peanuts when we were watching video or movies or whatever. We used to hang out 4-5 guys and do that like every night. My friend would always have his little bag of peanuts, and the rest of us would always pester him for some. Then one day he brought a gigantic bag of peanuts. And the rest of us thought "yeayy..we get to eat lots of peanuts tonight". Then he said "guys, look at this" and he took a peanut and put it up his nose. Then he blew it down into the bag, and shook the bag a couple of times. Then he said "Eat as much as you want guys". He was a smart guy.
