[flashback to 1982 where a young Ted is building a Lego skyscraper:]
Future Ted: [v.o.] Some kids dream of being astronauts. Some kids dream of playing baseball. When I was a kid, I had only one dream. To build a skyscraper.
Boy: That's stupid. [destroys Ted's tower]
[present day:]
Future Ted: There were some obstacles along the way. But eventually my dream came true. I became an architect.
Ted: Morning, everyone! So, I had an idea for the atrium. Ready? Columns.
Mr. Druthers: That's stupid. [destroys Ted's model]
