Do You Have To Be Black To Understand This Joke?

Dear Mo

Did you see this interview?   They were asking Jameis Winston about why he was squinting so much in his last game.   He said his eyes were thick or something?  Well Spencer Tillman and Brian Jones went bananas.  Like late night at the Apollo type shit.  I honestly have no idea what the joke even was.   Is that because I’m a white?  Or do black people not even understand what just happened?  

Thanks

Pres
