How is that possible? Couple sleeps during Strikeforce event

The party couple sitting next to me cageside at Strikeforce: Fedor vs Rogers in Chicago, IL. Totally passed out. Not sure how long they had been up prior to then, but they got their fifth wind (my guess) afterwards and woke up eventually, lmfao. As they say down here in the Durty Durty: Party like a rockstar!
