How many neutrinos does it take to change a light bulb?

Fresh after the news of the possibility of neutrinos traveling faster than light (although so far only in Italy and Switzerland, not anywhere else in the universe), a few jokes have started to emerge.

The barman says "We don't serve neutrinos here".  A neutrino walks into a bar.

and

Neutrino
Who's there
Knock knock.

The old styles are the best are they!  My attempt to create a light-bulb joke for neutrinos was so unsuccessful that I thought it best to invite your contributions in the comments below.

See Indecisive Neutrinos (3rd October) for more background, but not an explanation about why these are slightly funny to physicists.

Only one but shouldn't we wait until the bulb blows first?

One neutrino says to another neutrino, "Have you got the exact time, please?". "Of course" was the reply, it's "6:20 and 43, 42, 41, 40, 39 seconds".

Trick question. The neutrino is not aware of the photon fail.

Sign above the bar in a neutrino bar,
"Free Beer yesterday!"

If I were a neutrino I wouldn't change that light bulb until it came back on.
