Oakland Raiders fan's sign sparks grammar check and mockery, not necessarily in that order [pic]

Maybe he was preparing to take part in the “Salute to Common Core” halftime show:

The person who wrote his sign should also go, according to some on Twitter:

S/O to the Raiders fan that made the sign "Your Fired". You'd definitely be fired with grammar like that…
