If you've ever dreamed of saying the words "By the power vested in me, I now pronounce you husband and wife (or husband and husband, or wife and wife)!" or wanted to have your wedding ceremony performed by someone who is not a complete stranger, then consider getting ordained over the Internet. It takes about five minutes, is generally free, and in return you can legally perform wedding ceremonies and be called Minister.
A well-known and popular way to be ordained online is through the Universal Life Church [1]. Nondenominational and nondogmatic, they charge no fee for online ordination, just submit your application and they get back to you within 24 hours. They also have a list of state-by-state legal considerations [2] to check out.
Once you're ordained, don't go crazy with the baptisms, OK?
