In Season 1 Episode 24 titled "English as a Second Language" of Community, when Jeff discovers and tells his study group that Annie was the culprit, he tells everyone to not look at her. Everyone closes their eyes except for Abed, then Jeff says - "She is the Ark of Covenant" to which Abed also close his eyes. Then he says - "Picture her as Paul Giamatti" and everyone says "Uggh".
So I don't understand the meaning of these two dialogues. What was there about Ark of Covenant that made Abed close his eyes and why everyone went Uggh when he said to picture Annie as Paul Giamatti?
