All of the class pics that try to do something either trendy or tell a joke that only the class gets are lame.
One of the best squadron pics that I have seen was actually from a P-3 squadron(someone on the board may have it or something similar) and had all the squadron members in "throwback" regalia and the picture was sepia toned. Everyone was in bags, some had leather jackets (unzipped, of course), some had garrison caps, some had khaki combo covers on, a lot of guys had cigars in their mouths. It looked really nice and everyone who saw it thought it was cool as shit. I think it was taken in front of the plane or in front of an old hangar or something. It basically looked like it was taken in WWII.
If you did something like that, it may not be funny because it doesn't have a giant dick in it or some joke having to do with a Will Ferrell movie, but others will think it is awesome and you will be glad you went that route when you look back on it.
