excellent wayne's world reference.
i've had some hilarious experiences over the years buying and selling homes. you think you 've seen the craziest person and then nope there is someone crazier
oh yea. think about it like this....the house is the only one in the world with that land, features, location, etc etc. literally the only one. seller needs to execute original deal or else they're gonna pay up some money. unless there is something with the buyers offer that wasnt completed. checks, signed docs etc. lied about their ability to actually close
