How do they do those "toasted" effects with the walls? [They put the camera very far from the actors, zoomed in. Then the cameraman approaches them slowly while zooming back. More info here: http://en.wikipedia.org/wiki/Hitchcock_zoom.]

I have a couple of questions about the part of the show where Kelso's dating Angie, Hyde's sister. Number one: How can Hyde's sister be black? And number two: How come she's even there? She moved to the same town? [In "Let's Spend the Night Together", Hyde discovers that the biological father he never met before is black. His father has other kid(s) with different mother(s). They could have been in town the whole time, it's just that Hyde never knew these people were related to him.]

Whatever happened to Donna's little sister (I think her name was Tina?) She was mentioned during the first season and we even saw her once, but I haven't seen or heard of her since then. Have they ever explained where she went? [Even though they appear in certain episodes, Tina Pinciotti and her other sister, Valerie, were written out of the series, much like Chuck Cunningham on "Happy Days." They are neither seen nor mentioned again.]

Red is shown in his WWII Naval Uniform. He has three medals on his chest. One of the medals (the far one on the right as you look at him) is a Commendation Medal. I was looking at the episode and it wasn't clear if the medal was a Navy or an Army Commendation Medal. They look very similar - the Navy medal is green and white with the bronze eagle as is the Army's (I have an Army one). However, the Navy's has two broad white stripes near the edges of the green ribbon while the Army's has several thin white stripes near the center of the green ribbon. Has anyone noticed which ribbon it actually is? [It's the Army Commendation Medal. You can notice the pinstripes in the center of the ribbon. The navy one has no pinstripes.]

This goes where Red give the puppy to Kitty. In real life whose dog is that? [It's Ashton Kutcher's dog.]
