The most intelligent show in Vegas, as these two -- magicians? Illusionists? Truth-tellers? BS artists? Tell you what, let's settle on geniuses -- put on 90 minutes of, yes, magic and juggling, but also acerbic comedy, mean stunts, and great quiet beauty. Looking like two characters out of Dr. Seuss, big loud Penn and smaller quiet Teller (to reduce them to their basic characteristics) perform magic, reveal the secrets behind a few major magic tricks, discuss why magic is nothing but a bunch of lies, and then turn around and show why magic is as lovely an art form as any other. We won't tell you much about the various tricks and acts, for fear of ruining punch lines, but watching Teller fish money out of an empty glass aquarium or play with shadows is to belie Penn's earlier caveats about learning how tricks are done -- it doesn't ruin the wonder of it, not at all, nor the serenity that settles in your Vegas-sensory-overload brain.

Penn & Teller's Top 10 Things One Should NEVER Do in a Vegas Magic Show--Penn & Teller have been exercising their acerbic wit and magical talents in numerous forums together for more than 25 years, and their show at the Rio is one of Vegas's best and most intelligent. We must confess that we couldn't get the quieter half of the duo, Teller, to cough up a few words, but the more verbose Penn Jillette was happy to share.

1. Costume yourself in gray business suits totally lacking in rhinestones, animal patterns, Mylar, capes, bell-bottoms, shoulder pads, and top hats.

2. Wear your hair in any style that could NOT be described as "feathered," or "spiked."

3. Use really good live jazz music instead of canned sound-alike cheesy rip-off fake pop "music."

4. Cruelly (but truthfully) make fun of your siblings in the magic brotherhood.

5. Do the dangerous tricks on each other instead of anonymous show women with aftermarket breasts, and/or endangered species.

6. Toss a cute little magic bunny into a cute little chipper shredder.

7. Open your show by explaining and demonstrating how other magicians on The Strip do their most amazing tricks, then do that venerable classic of magic, "The Cups and Balls," with transparent plastic cups.

8. Treat the audience as if they had a brain in their collective head.

9. Allow audience members to sign real bullets, load them into real guns, and fire those bullets into your face.

10. Bleed

(You will find all 10 of these "don'ts" in the Penn & Teller show at the Rio All-Suite Hotel and Casino.)
