Firefly - I'd roll my own, but the cast hasn't gotten back to me yet
McDonald's Arch Deluxe - (not a big fan of McDonald's, but that was a great burger... as far as piss-poor quality fast food goes)
The 90's - Do I need to explain this one?
Young George Lucas
Douglas Adams
Semi-enjoyable airport experiences - (including meeting people at the gate)
Stanley Kubrick
Bulky cell phones that pre-date text messaging
Horse drawn carriages and your own two feet as primary forms of transportation
The days when you could easily live off the grid, because there was no grid
People actually having to meet face to face in order to socialize

I could go on forever... but, uh, yeah...
