Little lost alien

A woman in the states has reported a close encounter with an alien grey. She reported that it appeared in a manhole, with the manhole cover balanced on it's head. Now I keep an open mind about such things, but really, someone's taking the piss. What i want to know is,

Why was it in the sewers ? Maybe it had lost it's anal probe, and was hoping to find it down there somewhere. Or perhaps the teleportation equipment was in need of calibration, and so depositing it in the sewer instead of the street.

What's with the manhole cover ? Those things are heavy! and the alien greys are all reportedly pretty scrawny. Pretty good trick. Perhaps it wasn't actually a manhole cover, for all I know flat metallic hats might be the height of alien fashion this summer.

Poor little bugger! maybe it was on it's way to the alien equivalent of the melbourne cup, resplendant in new metallic flat-hat, but due to a transportation error found itself in a mid-western US sewer instead, oh dear.
