Since I opened my store 2 months ago I've heard THOUSANDS of comments like this:
1. "You must be uh mathmamatical genius!!!"
2. "I'm going to kill you!"
3. (for the V-7) "Do you make these? It says V." (because he saw my business card and my last name starts with V)
4. "Did you know Mr. Rubik was in the insane asylum when he invented this?"
5. "Can you fix all 9 sides?"
6. "I bet you can't solve this in less than 20 seconds." (19 seconds later... $20 later

)
7. (person barely scrambles cube) "Here I mixed it really good!" (5.66 time)
8. "Will Smith is like the fastest Rubik's champion!"
9. "Isn't there like some mathematical equation to figuring these out?"
10. ****!!! (person screams in my ear) OMG **** NO... HOLY ****
I went out to dinner with my wife one night at a pizza restaurant and an entire college soccer team (25+ people) shows up just as I finish a 3x3 solve. They're eager to watch me do another solve. So a couple of them scramble it "Be careful he's looking!" And several of them take out their camera's and timers. They all gather around the table to watch me do a 25 sec solve... after that they all jumped and screamed like crazy! Saying they want to put it on YouTube because it's so amazing and they'll get like viral views... then after that they wanted me to teach them... ugh
