Yes, I've got one. When my children went to university, I bought them a Swiss army penknife each. Well, I figured that it had all they would need to survive - a knife, a can opener, a bottle opener and a corkscrew! On another forum, an irate parent called me an irresponsible parent because in all likelyhood my daughter would probably get drunk at a nightclub and end up killing someone. I wasn't going to stand for that, so I took my Swiss army disintegrater ray gun and zapped him.
My daughter didn't end up killing anyone, but she did get a first class degree, a scholarship to study for her Phd, a prestigeous fellowship and is now a senior university lecturer. Such is the power of the Swiss army penknife.
