The video above makes it to season 9 showing he is 15 years old at this point.
With 11 more seasons to go, how old do YOU think he will end up being?
I'll try to keep an eye out for when the second part of the video is posted to find the answer.
He has done some really good research so my hat is tipped to that... Though I don't wear hats...
My cat ears are tripped to that... I occasionally wear those... Don't judge me...
