It would all depend on the person - - their interests & their attention span mainly. For example, I wouldn't put a technical clinic on for someone with severe ADD for example (but go figure, I've got ADD myself...), I'd show them something with a lot of fast action & high spots. I've spent the last 5 & 1/2 years trying to convert my girlfriend, and she seemed like she was getting into it for a bit - - really into Rey, and when DX reunited to go against Spirit Squad (she was even doing crotch chops for a while), but it didn't last, so I'm back to spending Monday nights alone again
Most of my friends are horror fans, so chances are good I'd break out some Undertaker classics. Between them & "Joe Average", it would be one of the following, whatever the situation calls for:
Undertaker vs Mankind, Hell in a Cell - It's got violence, suspense, high spots, and "Oh Shit!" moments galore. It'd be hard to go wrong with this one.
The first Money in the Bank Ladder match - High flying, fast action, and a dose of several different superstars with a variety of styles, it's like an appetizer sampler platter from Applebee's - - In other words, there's got to be *something* that they'll like it in it!
Steamboat vs Savage, WM III - What needs to be said about this one? Perfect to show any sports fan that isn't into wrestling. There's no way they'd be able to walk away from this one without anything but respect for these two athletes.
Orton vs Foley - The Hardcore match that gained Orton a lot of respect. One of my favorites. Maybe that makes me biased. But it's a great match & a good way to introduce someone to one of the current faces of the company.
Cena vs JBL, I Quit Match - Great way to introduce noobs to the OTHER face of the company.
