The barman said, “We don’t serve neutrinos here!”
A neutrino goes into a pub, faster than light.
Well, I thought it was funny, I’ll get my coat!

Boadicea's Chariot 
There was a young lady called Bright
Who could travel much faster than light
She departed one day in a relative way
And came back the previous night!
gads, Bearsy, I haven’t heard that one since the VIth Form. (Or year Zero, or whatever they’re calling it these days.)
To her friends, that Miss Bright used to chatter,
“I have learned something new about matter,
My speed was so great
That it increased my weight;
Yet I failed to become any fatter.”
