Me, too. Sometimes I find things amusing, which is different from funny or hilarious, but "How droll" or "How amusing" aren't much used expressions these days, so "That's hilarious" suffices to let the person know you're grinning on the inside. Unless of course it's really not funny at all, but you're trying not to say so and signaling that you appreciate the other person was trying to be funny.
