Update at 6:28AM on February 25, 2010: Congratulations to Chris from Carmel, Indiana for being the lucky recipient of two MythBusters T-Shirts!

Update at 6:12AM on February 17, 2010: The first person we selected did not respond within seven days; so we randomly selected a second person to receive the two MythBusters t-shirts. We are now waiting for that second person to respond and claim the giveaway.

Update at 6:32AM on February 10, 2010: Thanks to everyone for taking the quiz and taking part in the MythBusters giveaway! We have sent an e-mail to the person we randomly selected to receive the two MythBusters t-shirts, and we are waiting for that person to respond.

Update at 12:01AM on February 9, 2010: The giveaway period is over, and we'll be contacting the lucky winner via e-mail. We'll announce the winner here as soon as we get confirmation.

Did you hear about the myth that Discovery is giving away a free trip for two to Comic-Con 2010 so someone -- maybe YOU -- can meet the MythBusters in person? Or the one that TV Tango is giving away official MythBusters T-shirts? Well, we're here to say that both myths are CONFIRMED.

If you're a resident of the United States, you can enter Discovery's Comic-Con 2010 giveaway in two easy steps:

1. Follow the MythBusters Twitter account here: @MythBusters. That's one entry.

2. To increase your chances of winning, once a day between now and 11:59 PM ET on Monday, February 8, 2010, you get more entries by tweeting (THE CONTEST IS OVER, YOU DON'T NEED TO TWEET THIS PHRASE ANYMORE. CHECK THE MYTHBUSTERS CONTEST SITE TO FIND OUT WHO WON!)

I entered the SUPERFAN Sweepstakes to meet the @MythBusters at Comic-Con 2010 because #IMASUPERFAN via @TVTango

At the end of the sweepstakes period, Discovery will randomly select one person to receive the trip for two to Comic-Con 2010. Find out more about the sweepstakes or read the rules for yourself!

Still want to win a Mythbusters T-shirt?

To enter TV Tango's giveaway, you should scroll down and take a one-question quiz about MythBusters.The person who enters the giveaway before 11:59PM (Pacific Time) on Monday, February 8, 2010 and correctly answers the question scores two (2) official MythBusters T-shirts. If there is a tie and multiple people answer correctly, then a single person from that group will be randomly selected to receive the giveaway. The recipient must reside in the United States.

At the beginning of the quiz, we do ask that you enter your email address and name (as User Name) so we can contact you if you're selected. TV Tango respects your privacy and will not sell, distribute or otherwise use your email address for any purpose other than to possibly communicate directly with you for this contest.
