When that episode started I was so confused.

"Mom, I thought this was Reading Rainbow."

"It is."

"But it's ST:TNG openings credits!"

"... huh. It is."

"And it's 330pm - ST:TNG isn't on until 7pm!"

And then Mr Burton comes on all Reading Rainbow about ST:TNG. Glitter in a glass of water, the whole deal.

"Oh, ok. I get it."

Watched both shows back in the day but somehow never saw this ep! Thank you for posting it.
