Over at Michelle McCool’s official fansite (michellemccool.net), they did a Q&A session with him in which Christian mentioned. Here’s what she had to say:

You have done autograph signings with the likes of MVP, Tommy Dreamer, Matt Hardy and Kane to name a few. Who has been the most fun to do a meet ‘n greet with? Got any fun stories from one of them you’d like to share?
Signings are always fun! I like doing them with Kane & Christian! I love the kids who are terrified of Kane, but obviously want his autograph. They come up with their heads down, barely looking up to make eye contact!:) Christian is really funny ….it seems like we are always laughing!
