Take a look at this picture.
At some point in his life, this gent decided it would be romantic to completely ruin his friend's wedding and steal all the limelight from someone else's special day.
As Jezebel points out, he even had the nerve to put his half-drunk beer down in front of the bride before he did it.
The bride looks far from pleased.
The people of Twitter and Reddit appear to be in agreement - you should never, ever, ever steal someone else's wedding for your own proposal. EVER.
Judging by these comments, what this man has done is essentially steal romance from his friends.
