Few new short jokes for Friday

I just changed my computer login password to "Alcatraz" and now the "Esc"button won't work?

My wife left me because of my addiction to touching pasta.
Now I’m feeling cannelloni…

I love my job.
Wife: But all you do all day is round up cows.
Farmer: What did you say to me?
Wife: You herd.

I am joining a secret society of electrical engineers. They just asked me to step into a large coil with a battery attached.
This is their current induction process.

Does anyone know how to get peanut butter out of hair?
I made myself a sandwich earlier.

When my father died, he wanted his ashes pressed into a record. It was his vinyl request.

I went to the doctor because every time I opened my eyes, I vomited everywhere.
He looked me over and said it was the worst case of see sickness he’d ever encountered.

Sir Joseph Wilson Swan

Died 27 May 1914 at age 85 (born 31 Oct 1828). English scientist, chemist, physicist and inventor, born in Sunderland, Yorkshire, who produced an early electric incandescent lamp. He began these experiments in the 1840's and obtained a UK patent covering a partial vacuum, carbon filament incandescent lamp in 1860. Swan's early lamps provided low light output, were short lived, and were operated from battery cells. Low voltage operation required relatively high filament current that necessitated that the power source be co-located near the Swan lamp. He also addressed the problem of photographic print fading and in the mid 1850s some began to experiment with a solution using carbon, perfecting and patenting the process in 1864. Thus Swan invented the dry photographic plate, an important improvement in photography.[Image: pencil drawing by M. Agnes Cohen, 1894.]
