Do you ever not feel like wearing pants?

We just got home from the party to celebrate school opening. As I sat down on the couch to do my work for tomorrow, I took off my jeans. DH looked at me funny and asked what I was doing. I realized I was just tired of wearing pants. Has anyone else ever experienced that? I suspect I'm really weird, but I just didn't want to wear my jeans any more! Plus I was too tired to get a pair of PJ bottoms.
