From TED:

The slam poet/tech artist/paper sculptor Rives does eight minutes of lyrical origami, folding history into a series of coincidences surrounding that most surreal of hours, 4 o'clock in the morning. This elusive hour, both very late and very early, appears often in art in literature as a way to describe the most extreme states of affairs. Rives -- aided by a nimble mind and extensive online research -- reveals 4 a.m. as an iconic moment, drawing hilarious historical connections.
