Stand up! You've unlocked the Celtics badge for showing your Boston pride. Watch the Celtics take on the Lakers in The Finals 2010 on ABC! "Go Celtics!"
Send a shoutout to friends on foursquare. The shout has to include "Go Celtics!" in the text to count. You do not have to checkin to a location as part of this shoutout.
Tip: You can only get the Celtics or the Lakers badge. The only way to get both badges is for the shoutout to include both"Go Celtics!" and "Go Lakers!" in the same shoutout. This has to be your first shoutout of this kind to unlock both.
