Mods didn’t let my other Lubavitcher jokes on, so let’s see about these:
How many Lubavitchers does it take to change a light bulb? Ehhh the old one’s still good…
How many Meshichistim….? The old one never died!
How many anti-meshichistim…? They prefer to live in the dark!
How many Russians? Two. One to hold the lightbulb, and the other to drink until the entire room spins!
