Can God make a stone so heavy that even He can't lift it?
This perennial brainteaser is actually answered in the Old Testament! In First Kings 14:11, the Lord tells Jehosaphat the Kindler:
"Now shall I answer this question of which you speak. And thenceforth let it be asked no more forever. Yes, I may wrest such wondrous creations as I please from among the winds and the waters, and frequently do I choose to do so, for also is it true that I have nothing better to do, what with creating the Universe and ruling the Heavens and watching over all who toil below. So verily, the Lord your God totally has nothing but time on his hands to help some ignorant redneck yahoos settle the world's oldest bar bet. Is there anything else? Can the Lord your God get you a mint or a hot towel? No? Are you sure? Then if thou wouldst be so kind, may the Lord your God get back to work? Really? Are you sure? Great."
