On Feb. 3, 2013, the Baltimore Ravens and The San Francisco 49ers will redefine sibling rivalry.
Yeah, yeah, there's that whole Super Bowl thing that night, but we're more interested in how the head coaches -- and brothers -- of the rival teams deal with the family affair.
It appears that Ravens coach John Harbaugh is dealing with the whole thing smoother than a pigskin: He's just taking this as an opportunity to prank his parents.
And considering the Harbaugh parents have a no-win situation on their hands (but, seriously, whoever wins is clearly going to be their favorite), they could use the laughs.
Our friends at NowThisNews captured the hilarious, near-successful prank. Watch above.
