Checking it twice

Santa’s making his list, checking it twice.
Too bad for John Bettencourt (now known as Paul Miller of Orlando, Florida) that he doesn’t check with the Witness Protection Program.
John wanted chocolate-covered truffles from his favorite online catalog store, but instead of using a new shopper ID, he used his old one.
Santa didn’t notice. But the crooked defense contractor that John blew the whistle on did.
A box arrived the next day.
“Mmmmmmmm… truffles!” John said.
He opened it, setting off the parcel bomb.
It wasn’t reindeer on the rootops, but bloody bits of John raining down on them.
