One of my old roomates used to date online as well...
One day he was meeting with a chick later, and he shows us her pic, same thing, pretty much head only... And we were like "dude, she's a chunker, look at her shoulders (she was wearing a tank top in the pic), and he didn't believe us...
So he goes for the date, comes back, and we're all waiting (house of 5) by the door... He comes in and stammers "she was a little... bigger... than I expected" and holds his hands apart to show... hilarious.
Maybe you had to be there, he went into this with no clue.
