Party Bus

Q: Today, on my bus, the radio was playing an awesome song. Everyone was singing along or yelling, "TURN IT UP!" There were a lot of hand motions going on, i.e. doing the wave, waving hands, etc. Everybody was getting into it. Then, at our stop, all of us ran out screaming. We raced each other to our houses, laughing and talking. What day is it?
A: Friday.
