I know one shouldn't apply logic (or facts) to jokes (and let me add I have smiled first before thinking, so thanks for that) but since it has started:

Saying 'you just killed Beethoven' is equivalent to the young boy in school who got an 'F' in mathematics and says to his teacher: "You did this to the future Einstein" (the name might be wrong, BTW).

And just to go on with the correction game: Hitler married Braun close to midnight 2 days before their suicide. So he could have...but he was quite busy those days.
