I found out a sentence 'That a teddy bear from 1996 is not an antique.'from a text book. There is an audio file of it as well. The actor said so, too.

The story was like: Eric and Tom got back from a trip, and found their apartment was messy. Eric thought that they had been robbed and said he lost his antique from his grandmother. Tom asked what kind of antique was. Eric said it was a teddy bear from 1996. Then Tom said 'That a teddy bear from 1996 is not an antique.'

It was kind of a funny story. I just wonder why 'that'and 'a' are put together.
