The puppet one was hilarious, especially with general Hammond and the making the gate spin. But I appreciated the Farscape one a lot more than fans who haven't scent, mainly because having Ben play Stark and Michael play John was hilarious and ironic considering. The Furling, was cute but too much like the Ewok's from Star Wars. Invisible Jack got old fast, but having him in the room when Carter was in the shower was priceless. The young SG-1 was Kinda sad, but completely true of stereotypical teenage shows. The Star Trek and Wizard of Oz spoofs were interesting. out nothing special. Although my favourite part of the episode was the insinuation that Jack was Cam's father from when they went back to 1969, that was the best part in my opinion. Those are all the parts I can remember.
Oh, and the wedding was a nice thought, and well we all want it to happen even though it most likely wont, we can still hope.
