Define Funny Versus Hilarious

Michael asked a question on this post:

“How does one define the difference between “funny” and “hilarious”? Is there a difference?”

My response is as follows:

“Funny is how you describe you falling down the stairs. Hilarious is how you describe your mother in law falling down the stairs.”

Now it seems to me that I may not be the first person to describe the differences this way, but either way it made me chuckle. To me I am “That Funny.”
