You're never too old!!!
Sesame Street is a great show for everyone!
I'm going on 33, and I still love it as much as I did when I was 2!
A lot of the jokes are geared to adults...no toddler or pre-schooler is going to understand "8 balls of fur" (great balls of fire) or "Polly Darton" (Dolly Parton)
They don't recognize Whoopi Goldberg, or The Spin Doctors when the make an appearance!
It's adult intertainment geared towards children!!!
My mother is 56, she has a Cookie Monster cookie jar, and a stuffed Kermit on her couch in the family room!
You are never too old for a great program like that! No matter what your mother says!
