I'm an ordained reverend of the Universal Life Church (also the SubGenius, but I don't mention that if I want to be taken seriously), it took all of five minutes. Trust me, it's not worth a lot.
An extremely easily foreable ID I found the other day is a Gym Pass. Mine is for the local military base gym and it has my name, picture, and age on it. The thing is, it's SOOO uncomplicated I could probably produce a decent fake without even leaving Wal Mart (use the photocopier, scissors, and laminate).
