These video are everywhere and we have posted many of them right here.  The below video might just be the best ever. Watch as Alexis is making an oral presentation to her class, when she looks up and realizes who is standing right in front of her. Her dad had just made it home from Afghanistan and wanted to surprise his daughter at school. I am giving you fair warning about her reaction....it will get to you and there is no avoiding it so, just let it happen and enjoy....this is priceless.
