Apparently thinkgeek.com’s 8 bit ties were a popular enough April-fools joke that they are actually going to become real:
“Hey! You! Quit emailing us to make this for REAL already ;) We promise, we’ll make it. In fact we are already working on it. You’ve just forced our hand! Click the ‘email me when available’ link above to get notified! Thanks! I guess the joke is on us this year :p”
Yay! If I ever wore a tie this would be the tie I wore.
