An image search for "Beaker" from the Muppets will soon cure you of thinking that.

This ^ all day long

Dunno whether he had a nibble but if you're gonna put your wrist in somebody's mouth, there's a fairly good chance you'll come across some teeth one way or another.
Its not like he moved his head to wrist, don't think he could move tbh.
So its looking like Hill gives him a forearm to the face whilst trapped on the ground, leaves his wrist hanging about the mouth area, gets to feel those teeth on his skin so jumps up and has a thrombie.
Gotta stop short of saying that Hill got what he was asking for because we obviously can't condone biting, but you gotta ask questions of Chris Hill, the same person that dropped a forearm in for FA reason is the same person that jumped up raging like a loon on some ref conning mission.
He chucked a similar wobbler under the sticks at magic, turning in to a bit of a dramalama Hill is.

When did Chris Hill turn into the biggest snowflake in rugby? So embaressing!! He honestly looks like he’s about to burst into tears at any moment. He had plenty of chances to lamp miloudi but didn’t even have the stones to do it. Pathetic. Hope he doesn’t get picked for The june test. On form he should be well down the pecking order

He’s been like this for a few years. He seems to be more concerned with slanging matches with players and getting his back up about small things and swearing at the ref and giving daft penalties away than he is just playing the game.

Saying that he had a very good World Cup for England without the burden of being captain like he is for Wire. Maybe he thinks he’s leading from the front with all this crap? I dunno. If he forgot about all the BS he’s still a cracking player.

Oh to be in a position to actually rest players!!

He's struggling being pack leader I think, just needs to get on with the job he's good at.

He's too smart to go and lamp him, he ran back in as he knew the ref would then review the incident. Hill clearly thought there had been a bite, even if the video disproves that, he was looking for a reaction from Hewer - don't agree with the practice, but plenty others do it too.

That said don't let that take away from the fact he's had a very good season so far, stats back that up and he's back to his 'normal' self following a drop off in 2017 - obviously he had a very good world cup. No doubt he'll be on the plane to Denver, I think he deserves to be too.
