From the front, Mr. 63 ALWAYS gets mistaken as a wooden rod.
From the side, he ALWAYS gets mistaken as a large, wooden plank.
It's just how he looks like!
Mr. 63 then made a decision - since he can't change his appearance, he might as well be the best damn wooden plank to ever exist!
So each day, he goes out with a happy message on his body...
How can you not smile when you pass him on the streets? :)
