Baltimore Ravens coach John Harbaugh has impeccable timing.
Moments after David Rudich proposes to his girlfriend Amy (last name unknown), Harbaugh crashes the couple's proposal at the team's training facility.

It's hard to tell what surprised Amy more.
Seconds after Rudich takes a knee, Harbaugh walks down a set of outdoor stairs to greet the couple.
"Let me shake your hand," the coach says.
Amy replied, "my hand is already shaking."
In the description on YouTube, Amy is described as a "huge Ravens fan."
The video ends with a group hug with the Super Bowl winning coach.
