Coworker 1: Check this out (shows us unlikely picture on internet)
Coworker 2: That's not real.
Coworker 1: Yes it is.
Me: No he's right.
Coworker 2: You can tell its photoshopped (goes in to technical details)
Coworker 1: No!

Coworker 1: No THIS is real! I can see a picture on the internet.
Me: I can show you a picture of the bridge too. (tapity tapity on the keyboard) See here it is on the internet.
