Note that some of these responses are from people who derive pleasure from subverting expectations.

• "Oh, it's not like, really creepy. It's just a little bit creepy. Go on, look!" (and variations on making the button pressable enough to make me press it)
• "But, this is definitely the most disgusting joke ever. Not just at the top of the list, man, this is like Bill Gates in Africa top of the list." (Bizarrely, trying to make the button more pressable by making it more banned)
• Blank incomprehension, the sort you'd get if you answered "mu" to a normal question. (Possibly they hadn't realised "I guarantee you will feel sick" isn't another way of saying "Check it out!")
• One specific comment was unusually clear: she said "No, do it, I want to say I told you so."

It is surreal watching people try to argue you out of taking their warning seriously.
