Kitty: [records] Anyway, Eric, the day you left, Steven went to Chicago to see Jackie.
Donna: When he got there, he walked in on Jackie and Kelso, who were about to...
Fez: Get busy. Have sex. [sings] Do it!
Donna: Kelso told us the whole story when he got back the next day.
[flashback:]
Kelso: No, hardly anything happened, okay. Jackie asked me to stay 'cause she was lonely and the next thing you know, I'm naked. And then Hyde shows up and kicks me out the door and so I had to drive all the way back here in this dress that I found. All the truckers were flashing their lights and honking their horns. It was pretty great.
