LBC host Nick Ferrari asked David Cameron about the infamous "pig's head" story while interviewing the former prime minister for his radio show.
A biography of Cameron by Lord Ashcroft and Isabel Oakeshott claimed that during his time at Oxford University he inserted "a private part of his anatomy" into the pig's mouth - resulting in the hashtag #Piggate trending on Twitter.
Ferrari asked: "Did another world leader ever mention it to you?"
'No," Cameron exclaimed, before recalling a recent incident.
"I was walking along the street with Elwen, my son, the other day and someone shouted a pig-based remark, if I can put it that way.
"Elwen is a sweet boy and people up until then had been saying some friendly things and he turned to me and said, 'Don't worry, Dad. On the whole people have been pretty friendly today'."
