In the same bookshelf?

I've gotten myself a new book. We are looking at options of doing in-house training, and I'm currently looking at material to use for that purpose, and I got this book as part of that quest. I got the MCTS Self Paced Training Kit (exam 70-503), Microsoft.NET Framework 3.5 Windows Communication Foundation.

Now online bookstores likes to find different ways to try to entice you to buy more, and one way they do this is buy giving you a list of other books that people in your situation has found interesting. What I found funny, and slightly scary was the suggestions that I got. In the same bookshelf of people who bought this book, apparently, are: Microsoft Office Excel: Step by Step and Online dating - all you need to know. The latter is circled in the included picture.

Somehow I just don't see it as being the same people that get these books - I mean, a .NET 3.5/WCF book and Excel step by step? Really!? But hey, maybe I'm wrong ;)
