On a tangent, the list of Liechtenstein-Switzerland military conflicts on Wikipedia is hilarious and kind of cute.
For example:
> On 26 August 1976, just before midnight, 75 members of the Swiss Army and a number of packhorses mistakenly took a wrong turn and ended up 500 metres into Liechtenstein at Iradug, in Balzers. The Liechtensteiners reportedly offered drinks to the Swiss soldiers.
