1 Erwin: I am still not convinced zeppelins filled with hydrogen are entirely safe, Herr Kolonel.
2 Haken: Didn't you hear about die Luftwaffe officer who thought die same thing? He took a train from Berlin to Paris und died in an accident.
3 Erwin: I had not heard this, Herr Kolonel! What happened to die train?!
4 Haken: A flaming zeppelin crashed into it.

An oldy but a goody. Surely there must be a reader out there who hasn't heard some form of this joke before.

No? Dang.

2014-12-02 Rerun commentary: Of course, nothing is entirely safe.

It's a wonder people survive brushing their teeth, sometimes.

Note: Do not brush your teeth with hydrogen. Sparks between fillings and the active ingredients in most common toothpastes can cause ignition.
