Tourists try to take group pic at Eiffel Tower, only to get photobombed -- by Arnold Schwarzenegger

A photo at the Eiffel Tower is a must for every tourist who visits Paris.

Well, that's exactly what one group of visitors did.

Little did they know however, that their group photo was about to be photobombed by a certain Arnold Schwarzenegger.

According to Acid Cow, the actor was riding a bike by the Eiffel Tower when he rode in front of a group of tourists trying to take a picture. 

At first they didn't recognise him, and couldn't figure out why someone was trying to spoil their photo. 

Then they realised who he really was, and sportingly allowed him to join them as they had their photos taken.
