Input: Question: A friend posed the following word puzzle to me: Can you think of a sentence that keeps the same meaning whether you use "it's" or "its"? He asserted that this puzzle does in fact have a solution. However, it has me completely stumped. I tried to solve an easier problem, to find a sentence which is still grammatical if you change an "its" to "it's", but all I could come up with is examples like "It's light!" (which is, strictly, more of a sentence fragment). What is the solution to the word puzzle? Or, is there some way I can "prove" that the puzzle should have no solution? 
Answer: The following took me about two minutes, so I wouldn't be surprised if it can be improved: "I can never remember what kind of fruit the tree in my garden has - until I look out of the window and see it[']s apples.".

yes
