Blind Man

Husband and wife are waiting at the bus stop with their nine children. A blind man joins them after a few minutes. When the bus arrives, they find it overloaded and only the wife and the nine kids are able to fit onto the bus.
So the husband and the blind man decide to walk. After a while, the husband gets irritated by the ticking of the stick of the blind man as he taps it on the sidewalk, and says to him, "Why don't you put a piece of rubber at the end of your stick? That ticking sound is driving me crazy."
The blind man replies, "If you would've put a rubber at the end of YOUR stick, we'd be riding the bus ... so shut up."

Johann Christoph Denner

Died 20 Apr 1707 at age 51 (born 13 Aug 1655).German inventor, maker of musical instruments and inventor of the clarinet. He made improvements to the chalumeau, the first true single reed instrument, of the late 1600's. He and his son Jacob are attributed with innovating the speaker key which gave the clarinet a larger register. The clarinet overblows at the 12th. That is, when playing a C without the speaker key, then add the speaker key, the note that sounds is a G, which is the interval of a twelfth. The other woodwind instruments overblow at the octave. The clarinet bore is cylindrical, whereas every other woodwind instrument has a conical bore (even the flute!). This is why the clarinet overblows at the twelfth and is so laden with overtones, which contributes to its unique sound.
