### Bowling Team

Two bowling teams, one of all Blondes and one of all Brunettes, charter a double-decker bus for a weekend bowling tournament in Atlantic City. The Brunette team rides in the bottom of the bus. The Blonde team rides on the top level. The Brunette team down below is whooping it up having a great time, when one of them realises she doesn't hear anything from the Blondes upstairs.

She decides to go up and investigate. When the Brunette reaches the top, she finds all the Blondes frozen in fear, staring straight-ahead at the road, and clutching the seats in front of them with white knuckles.

She says, "What the heck's goin' on up here? We're havin' a grand time downstairs!" One of the Blondes looks up and says, "Yeah, but you've got a driver!"

### Pasteur's rabies vaccine

In 1885, after 15-year-old Jean Baptiste Jupille was severely bitten while with his bare hands he killed an attacking rabid dog to protect five other young shepherds in Villers-Farley, France. He shortly became the second person treated by Louis Pasteur's experimental vaccine for rabies. He was fortunate to be taken to Pasteur's laboratory. Pasteur's collaborator Emile Roux had thought of attenuating the power of the infection by exposing strips of fresh spinal marrow taken from a rabbit that had died of rabies to dry, sterile air for various lengths of time. The vaccine was a small piece of marrow ground up and suspended in sterilized broth. It had first been used on Joseph Meister on 6 Jul 1885. By 12 Apr 1886, 726 people had been treated.
