Not Funny

No, you can't catch Elwetritsche with a vacuum cleaner, no way, electric or not!!!
Unbelievable what one gets to look at these days downtown Kaiserslautern. Silly electricity company...

Just in case you forgot, this is the only way to catch one (in nights of the new moon only - but not me - I'm way too smart!):

Elwetritsche Hunt (source: Wikipedia)

The Elwetritsch is supposedly very shy, but also very curious. A hunting party consists of a "Fänger" (catcher), equipped with a big potato sack and a lantern, and the "Treiber" (beaters). The catcher is led into the woods where the Elwetritsch is supposed to live, instructed to wait in a clearing with his sack and lantern, while the beaters go off, supposedly to flush out the Elwetritsch. The light of the lantern is said to be attractive to the curious creature, so it will come to investigate and will then be caught by the catcher.
