Gee thanks ThaMan. It's good to see that somebody around here uses there imagination to create a plausible explanation, instead of asking why Goofy is wearing glasses and why is he biting his lower lip. Anything, really, is possible. Whatever you imagine, it's happening.
Mmmmm... @$$... B'way, didja know that Goofy got his voice thanks to clarinetto player in the Disney Studio orchestra called PINTO COLVIG..? Once they heard him laughing aloud, the now famous 'ah-yo, ah-yo, ah-yo, ho-ho-ho-hoooo!' and the legend was born..!
