If you don't find childish humour all that amusing, let us warn you now: this isn't the prank call video for you.
This clip comes from the Washington Journal show on US political channel C-SPAN - a long-running programme which regularly sees viewers from all walks of life call in and ask questions of its guests.
This particular viewer purports to come from Portsmouth, New Hampshire and has the alias of "Dan".
He starts by feeding former New Hampshire Governor Judd Gregg a bunch of nonsense about understanding what Gregg is "going through at the moment" before unleashing a highly awkward question.
A highly awkward question... about presidential candidiate Mitt Romney's penis. The same Mitt Romney that Gregg is on the show to support. That Mitt Romney. That penis. Ah.
The resulting embarrassment is truly a sight to behold, so we're just going to let you get on and behold it. Deep breaths now...
