You don't question the H-Man, the H-man questions you.
That being said, if I could question the H-Man, I'd request permission to try out some nicknames I have for him, such as "Mr. 8" (since H is the 8th letter of our Christian alphabet), or "H-Man, the Living Death that Talks." I'd also like to go around saying "I heard it on the H," if that's alright with you, sir.
