How many Talmudic scholars does it take to change a lightbulb?
500. One to make the argument that the lightbulb MUST be changed, due to a verse in the Tanakh (Old Testament), one to make the argument that, under an obscure passage of Torah (Pentateuch), the lightbulb must NOT be changed, one to make the argument that the lightbulb can be changed or not changed, as anyone wishes, one to have a completely obscure and impossible to understand point that is, well, impossible to understand, 495 to argue for a millennium over the issue, and one to hire a shabbus goy to change the darn lightbulb.
