Hiccups?

Today at work I was sitting at my computer and eating lunch. I kept feeling these little twitches, more like a small spasm on my left side. It wasn't a kick, it was very quick, but repetitive and it lasted for a few minutes. I realized it about a minute after it started....Cletus was having hiccups! It was pretty funny. He/she hasn't had any since then, but I've read that they'll pick up in frequency during the last trimester.
