I will tell you guys one thing I did with a (then) witness friend of mine.
I was invited to go on a camping trip with him and his parents to France. Beautiful weather took us to the coast where we visited some WW2 bunkers. Now his parents allowed us to roam freely and we agreed to meet later that day and go back to the camping together. We went and bought firecrackers at the tourist stalls to use later back at the camping. There were several sizes availlable, we bought some medium sized ones and two packs with crackers the size of dynamite sticks. Thick, large and red was hard to resist especially since fireworks are not available in the Netherlands except at newyear's eve.
We were browsing around the bunkers when our attention was drawn by a German tourist that was 'entertaining' his kids by making machinegun and bomb sounds. It started to annoy the hell out of us hearng constantly "rattatatatata!" "piiiiiiiiiewwww BANG!" "ARRRGGG!" and such battle sounds. We saw them enter a particular dark bunker that was partly flooded so you had to walk on a narrow plank. As soon as the guy was in he started the noises again entertained by the echos it gave. He and his kids were struggling to maintain balance on the plank in the dark. This instant we both looked at eachother with a huge, evil grin on our faces. We moved up outside the bunker to reach the gap through which in times past the soldiers would shoot from. I take my lighter and light the biggest stick I had and threw it in....
"piiiiiiieeeewww" "ratatatatata" "piewww - WHAMMM!!! AAAAAAHHHH!!! SPLASH!!!!! SPLASH!!!!! SPLASH!!!!!
We were laughing our butts off, and this naturally made the German conclude we were the guilty ones. He persued us in a raving frenzy but finally we lost him by hiding in the parking lot. We were relieved when my friends parents came and we returned to the camping site. HOWEVER, when we took a shower later that night and returned dripping wet and laughing still about the incident we met our new neighbours. We had already seen their trailer but had not met them yet. Guess who it was.....
Yep Jawohl! The German.
