A Shrek fan has pointed out an X-rated joke that went over their head as a child.
And many fans of the popular film, cannot watch it in the same way ever again, the Mirror reports.
The much-loved film, released 20 ago, follows Shrek the ogre as he rescues Princess Fiona from the highest room in the tallest tower of a dragon-guarded castle and (spoilers) the pair fall madly in love.

A second said: "My last 1% of innocence I had just left my soul."
A third wrote: "I will never forgiver you for this" and a fourth commented: "The fact that they actually put time to animate that."
Another added: "I DIDN'T REALISE IT RAISES OH MY GOD NOOOO," and someone else admitted: "When I was younger I thought he spilt his drink..."
