Who Wants It More?

Plot:

Lovers Eric and Donna were the perfect study partners, but he falls over his own words into dumping her over an arms race disagreement, then is easily seduced. Kelso thinks he saw an UFO, Hyde nor Fez believe him but are greatly amused by his nude pictures on the same roll Leo brings over. Red imagines being killed by neighbor Bob Pinciotti's tree-pruning and turns human to the point of throwing a party. Sex blackmail sounds as an epiphany to Midge, but Donna is relieved when Eric finally makes up.
