Obviously “in his buttocks” is not where it was “lodged”.
If it had lodged where you imply, his intestines would have been ripped to shreds, and he probably would have died, not have left the hospital in three days. Not only does he suffer a grotesque injury, he’s the subject of jokes and lewd speculation.
I don’t know why the LA Times is bringing this up now, it happened almost three years ago. A perennial favorite, I guess.
