Best HET comedy/magic in your opinion?

I am making plans to purchase the Harrahs $99.00 all Stage pass (48 hours to see all the HET shows u can see). Since comedy is my favorite type show with magic/old skool music a close second ( although I must admit the Chris Angel show last year was the worse magic show I ever seen), I thought I would seek some opinion(s) on the best comedy/magic acts amongest the following......
Mac King
Vinny Favorito
George Wallace
Improv at Harrahs
Defending the Caveman
Nathan Burton
Dirk Arthur
Anthony Cools

I believe that I could make 8 shows in 48 hours. (If I get my 48 hour pass on Tuesday 8/23 - at 10 p.m. right before the 10:30 p.m. Improv at Harrahs). I've been doing research!!!

My wife and I love the Mac King show. We've seen it twice now(didn't see it last year).
We also saw the Vinny Favorito show(last year). In my opinion that was one of the funnest shows I've ever seen in Vegas. I was in tears half the show.
I haven't seen any of the other shows on your list so I can't help you with those.

Mac has just a wonderful Show but it's such a family Show too...
Ya can't beat the price and it's never a problem getting a free pass
for the cost of a drink so, I'd pass on that...see it on your own and
use the Harrah's deal for more expensive Shows.
I HIGHLY SUGGEST PENN AND TELLER...VIP SEATS!

Thanks vegas777 for your feedback. It's obvious that Mac king should be on my list somewhere.

I dont think Penn and Teller is included in the 48 hr pass ( unless u have a trick for me?!). I'll do the drink thing for Mac King! Thanks Gregrio!
