How do I open this soda?

I put a bottled soda in the freezer. I did not expect it to freeze as fast as it did. Its pretty much thawed now (been out of the freezer a little over an hour) but because of the pressure inside, I can't get it open. Several people in my office have tried. If I wait longer, will the pressure go down? Or should I poke a hole in it? The latter sounds like a messy process. Has anyone else ever had this problem?
