Grant Wahl is a Fox Sports television correspondent and writer for Sports Illustrated whose Twitter handle, @GrantWahl, provides his followers with in-depth soccer analysis. The handle @GrantWahlsHat is a parody account that doesn't provide much of anything useful aside from hat-related jokes.
Fox recently aired the wrong account as Wahl's on air, resulting in what is probably the most traffic this account has ever received.
Wahl's been known to tweet at the account, which is poking fun at the fact that he often wears a hat to protect his bald head from the sun.
Here are a few of the tweets you can see on the parody account.
