I don’t usually laugh when I’m watching or reading funny things when I’m alone. I might think “Ha, that’s funny” or I might even smile, but I rarely ever actually laugh.
Russell Brand is one of the few people who will make me laugh regardless of who is (or isn’t) around me. I’m watching the second series of Russell Brand’s Ponderland right now and I’m actually laughing out loud. I mean full-bodied, audible laughter. It’s scaring the cat.
