Personally, not my cup of tea. I wouldn't really call them punk, as they are more rock. I can see why people like them, but personally I don't think they're all that great. They have some good songs, but try too hard to be rebellious. Honestly sometimes I think that they are making fun of punk rock. I think they kind of try to be like Anti-Flag and Pennywise (real good punk bands) but instead it comes out sounding like pop music. That' s what it is. Pop music.

According to Charlton Heston's 1973 film Soylent Green, green day would be Tuesday. That's the day you get your rations of soylent green. Water and the other crap is given out on other days. Bulldozers mow people down every day. Oh yeah, and soylent green, which you'll get on a Tuesday, is made from people. People!!

Greenday is actually the definition of the earliest calendar day for appointments. For instance when you book an appointment with your doctor the earliest day available is the Green Day **Green for go**
