Now I wouldn't say some of those questions were hard, but not all are common knowledge (granted I could answer 99% of them) but when you watch this then compare to the people they get on the show "Street Smarts" it REALLY makes you ashamed.
That is too funny. I'd reply back something along the lines of...
"Oh my goodness, I'm so sorry that this happened. I'd be glad to replace the links, just let me know which pictures it is you were using and I'll put them back."
Then put pictures of goats and other farms animals up instead, as well as a photoshopped picture that says "I'm too cheap to design or pay for my own pictures, so I steal from others then cry when they don't let me." But that's just me.
