Being shot never was anyone's idea of a good time, but at least most people who got shot still have a head afterwards.
The guy wasn't in good shape after getting shot, but look at what happened to the guy that got decapitated. He had a bad night.
You watch a decapitation just once and you might get sad or feel something else (fearful, angry), but you watch it 5 or 6 times and you see the humor in it, which is why instant replay makes sense for something like that.
The instant replay decapitation was a crowd pleaser.
Another form of the phrase "losing your head", which means to have gone crazy.
The new guy is gonna decapitate me with his corny jokes!

-Bro! What happened to your penis?
It's still in good condition. She only managed to break the condom.
