This comment is null. At least, that's the hypothesis.

The most interesting thing about the t-test was that it was created by a chemist for the Guinness brewery in Dublin in 1908.

Also interesting are the other appearances of Belle and Mr. Whiskers which happened here, here, here, and here.

That means the last one was four years ago. Should I have left them in the past?

Or call this Old Character Re-appearance Week! and ride a nostalgia train?
