Sports rivalries can break friendships, or make them stronger by trolling one another.
That's what has been happening for John Krasinski and Jenna Fischer during the Stanley Cup playoffs.
John is a Boston fan and Jenna a St. Louis fan, so the rivalry has been HEATED to say the least on social media.
Jim Halpert took to Instagram last night to troll Pam before the game.
Wait a second.. Is that Pam's ex-fiance ROY?!?
Jenna's response, “Ha. Ha. Ha. Well played. Just be careful he doesn’t leave you at the game.”
PAM AND ST.LOUIS BLUES FOR THE WIN!
Congrats to Blues on their first win and to Jenna for trolling right over John until hockey season starts up again!
