I don't really know. What I do know is that he was cast in 1993, his birth having been announced in 1985.
I dont see anything about his favorite number, but i know he wa born in 1985. nothing to do with the number 7 though :/ he was cast in 93 for the show.
Seven is my favorite number! That's great! Speaking of 7, since 1997 Eric Jacobson has been the primary performer of Bert. I did not know that! Do you know why other people think it's a lucky numbe? I'm not sure. However, I do know of a character on General Hospital named Lucky Spencer. That would be a neat name, does Lucky like the number 7?
His birth having been announced on-screen in 1985, a ten-year-old Lucky was cast in 1993, played by newcomer at the time, Jonathan Jackson.
