GuyRule #285.0: TV Notification
If a truly great movie is on TV (i.e. any Mad Max or Die Hard movie), it is mandatory to call at least one other guy to tell him. This also applies to incredibly hot women.
Corollary -- if you fail to do this in the case of a hot woman, it is totally improper to tell the other guy about it later. If it comes up, tell him you caught it, but just the very end. You were going to call, but it was over before you found the cordless.
