The first time I met my girlfriend, I made her laugh and heard a loud but distinct squeak. When I asked her “Did you just squeak?” she smiled and said “I squeak when I laugh…” I was about to say that I thought it was cute, when she added “Loudly, and like a balloon.” with a big grin on her face. Which is how she found out that I snort when I laugh. My roommate tries to get both of us laughing so he can direct the symphony of silly noises.
