HA! yes, i am quite sure they are. I wonder if heaven has a stolen halo APB system like mortal law enforcement maintains for hot cars. Everything tells me that somewhere in a broom closet in the dungeons of hell there are two heaven messengers trussed up and gagged while these two impostors take an opportunity to see how the other half lives. I fear if St Peter grimaced, cleared his throat, and tapped on the no smoking sign, the one "angel" might well light a new cigar up as her companion crushed her's out on his pen hand.
