i heard of a prank in which a (non jewish) person was taking some else on a date in yanke stadium. he had a bunch of (?friends?) that were following him and they paid for a feww secondes on the screen to say “<girls name> will you marry me , your love <guys name>” or something similar and she said Yes and the guy didnt want to marry her. It must have been hilarious.
so i guess that here the Guy said no (not what u were looking for but he did say no to a Marriage Proposal).
(note: i an not approving this prank, i think i was horrible, and i would NEVER do it, how ever i count resist posting it)
