Go here (do it) and then here (do it!) and then come back.
My Dad is the coolest guy ever - you just read the reasons and the confirmation. Today the earth has been blessed to have him on it for an entire 50 years. That's pretty darn cool - just like my Dad.
I would like to make a point about his coolness - he has been deemed the coolest guy ever. That means that no matter who comes along they will never be as cool as Dad because he is the coolest guy ever. Egh-Verrr.
Happy Birthday Dad, I love you and I'll see you on Sunday night (or next Monday morning).
