Bumpkin Ate Human Flesh!

This groundhog likes the taste of human flesh.

I came home one fine day.  After saying hi to Bumpkin, Lucinda, and Sloopy, who were watching Groundhog Day again (How many times have they seen it?  I lost count, but it's well over 100 times for sure.), I changed into my pajamas and slippers.  Then I went to the fridge to get some cold water.  I opened the door, and there it was: a human head!  I screamed like a little girl.  I couldn't help it.  Then I heard it: laughter.  Bumpkin, Sloopy, and Lucinda were laughing their little groundhog heads off.  I slammed the fridge door shut and marched to their bedroom.
"What have you done this time, Bumpkin?" I asked.
"Hey, watch your tone, buster!  I'll forgive you this time, because you screaming like that is the funniest thing I ever heard!"  She cracked up laughing, and she was joined by Sloopy and Lucinda.
"It's not funny, Bumpkin.  I assume you killed that guy.  You're going to get us into big trouble."
"The harder they come, the harder they'll fall.  If they want to come after me, they know where to find me.  Anyone seeking vengeance against me will suffer a similar fate."
"Where's the rest of him?"
"We ate him," replied Bumpkin.
"Wow.  How did he taste?"
"Pretty darn good."
"I don't really have a problem with you guys eating human flesh.  After all, people eat all kinds of animals.  Who am I to say that animals shouldn't eat people?  How did this all happen?"
"There was a knock at the door.  I ignored it.  Then I heard the door unlocking and opening."
"Uh-oh," I said.
"As I was saying, I heard someone come into the apartment.  So I came out to investigate.  This guy was standing there.  He just stared at me like a big dummy.  I knew I had to snuff him, but I didn't want to make a mess in the apartment."
"Thank you."
"So I used my powers to open the window and screen.  I tossed him outside the window, and kept him suspended in midair.  Then I separated his head from his body.  I let the blood drain out of his head, then I put it in the fridge as a joke for you to find."
"Good one.  You got me."
"Obviously.  Then I burned his clothes off with a fireball.  And then I cooked him with another fireball at 400 degrees for about an hour.  He was delicious."
"Excuse me for a moment please," I said to the sisters.  I walked back into the kitchen and opened the fridge.  Sure enough, I recognized the man.  He was one of the maintenance workers at the apartment complex.  Poor bastard.  He was just trying to do his job.
