New England Patriots tight end Rob Gronkowski really is a polar bear who catches passes from Tom Brady. He's plenty of other neat things too, but let's not distract from the message about to be inserted into your cranium.

Rob Gronkowski is threatening Tom Brady.

Sound the alarms! Call the police! A giant human is going to hurt a slightly less giant human with his huge paws!

This is over biscuits, for what it is worth.

Brady posted a nostalgic Instagram picture of him making his grandmother’s biscuit recipe on Thanksgiving day and then raved about the biscuits to reporters on Friday. Our giant polar bear friend heard this, then immediately declared that all food should go through him (and his mouth).

“He (Brady) was bragging about them (Friday) and I told him to bring some in and he’s like, ‘They were so good they were all eaten,’” Gronkowski said according to Ryan Hannable of WEEI.com in Boston.“So I told him to make some more. I’m not lying. That’s dead serious what happened.

“If he doesn’t bring some in there’s going to be some problems.”

This seems like a real — cough — issue to the polar bear. Brady best get him those biscuits or else.

Also of note, for those who don't enjoy bad dad jokes, none of this is serious. I mean, Gronk's quote is real and all that jazz, but he isn't going to actually hurt his future Hall of Fame gunslinger over some biscuits.

We don't think…
