As far as I know, common point for majority here is liking expansion and, particularly inflation. Thanks to captain Obvious for that great revelation.
That is funny and even appealing, though another aspect attracts me much more: being inflatable (either me or other people) living, sane, mobile and in the same moment filled with air, with inflation valve. Hence possibility of inflation over normal size, or deflation to the state of empty crumpled heap of latex. It is not that important.
