An 89-year-old married grandfather posed as a 21-year-old hunk on Tinder.
The American man, who is known simply as Joe, secured the dates with attractive younger women after posing with the help of his grandson Ethan.
A video clip of the prank has been posted on YouTube and sees Joe ask his unsuspecting dates: ''I'm shocking you am I?''
Following some awkward small-talk, Ethan enters the restaurant to apologise to the women, in the hope they will eventually agree to go on a date with him instead.
However, the majority of the women leave looking very confused.
