Sorry, correction:

//Are you familiar with the old analogy about explaining jokes and dissecting animals?//

Should be:

\\Are you familiar with the old analogy about explaining jokes and vivisecting animals?\\

My bad.

Toni,

What joke did I not get?

//Toni,

At this point, I reconsidered explaining the actual joke to you. I still decided not to, because spoilers.

The analogy about explaining jokes and vivisections goes like this, Mr. Iceberg lettuce:

"Analyzing humor is like dissecting a frog. Few people are interested and the frog dies of it."
-E.B. White

Although technically if the frog wasn't dead to start with, it's vivisection rather than dissection.

Tiger,

I assume that the joke has something to do with John Cleese?

If so I'll need an explanation as, aside from 'Faulty Towers', I'm not familiar with his work.

Some time has passed since the last sign of activity.

Well, no one could satisfactorily answer the question as to what school teachers could do to defend themselves from a killer in their school.
Those who argued that a teacher could have their pistol taken from them and that it could be used to kill were obviously arguing from a position of ignorance as Smart guns have been available for at least 50 years.

A Smart gun (for those who didn't know) is one that is electronically/magnetically/whatever, set-up so that only the owner or other designated person, can fire it.

This seems to be the latest:

Issy,

Since the mass shooting at Pumpano Beach, 10 people have been shot dead in the US by random shooters along with 38 injured. In Detroit Michigan 4 people were shot dead at two locations including two people at a gas station, they were shot by a man while filling their car.

Just another day at the gunnie office, right Issy.
