Face Book Intermission - a brief respite from the philosophical, intellectual, cultural, family-oriented, self-centered, political, food-tripping, ego-tripping, arrogant, creative, opinionated, plagiaristic, bla, bla, bla posts, comments, and shares in Face Book. Often, but not always, the F.B.I. is about a term derived or influenced by U.D. (Urban Dictionary). Sometimes the term is posted first in F.B.I. before it appears in U.D.
I'm tired of all these pictures and comments from my ex-girlfriends and ex-boyfriends... I'm now ready for F.B.I.

They also have a nationwide web of phone/webtaps, informants, spies and undercover guys ("plants"). Founded in 1908 with the purpose of fighting crime more effectively nationwide, they eventually lasted through trying times such as the Prohibition, WW1/WW2 and 9/11 and continue their work today.
