Patrik Berglund hasn't had the best of seasons - he's been stuck on one goal since the Blues' victory over the Florida Panthers on October 5th. Here he is, against the Islanders, teeing one up, and... oops.
Brian Elliott (and probably everyone else who saw it) found it quite entertaining.
Berglund tried to cover it up as an "ice problem" in the intermission interview. Suuuure. That's what they call it nowadays.
