#1 ichiban ever Father's day most glorious dad

I always loved those Wildwood boardwalk shops with iron-on transfer t-shirts when I was a kid. Sure they had Gremlins and Transformers to E.T. and NKOTB. It was the easiest and quickest way to get topical summer attire to make your statement. 

I remember my dad had a #1 Dad t-shirt. It was super thin and pretty tight, and would fit in great walking down the strip. Was he the #1 Dad? I mean, who could claim that, and by what measures are we going by? Who is voting? Lotta questions...little answers.
