Who created the whole 'TGIF' movement? How long have people been saying it? I feel like it must have started in an office with this incredibly annoyingly cheery guy that went around doing the double guns and saying 'TGIF, buddy!'. And apparently there was one soul in that office that found this manic hand gesturing guy cool and thus, aided him in establishing the TGIF phenomenon by spreading the gospel according to office nightmares everywhere.
