The setting: Owen has built an obstacle course for his trains made out of Legos, placed on the coffee table. He has given Jim the yellow train named Molly and has assigned himself the silver train named Spencer.
Owen: Hey, Molly!
Jim (in a high falsetto imitating a girl): Yes, Spencer!
...Owen seems taken aback, then restates his greeting...
Owen: Hey, Molly!
Jim (in falsetto again): Yes, Spencer!
...Owen turns to get up, muttering to himself "I've got to get a boy train, 'cause Molly's freaking me out!"....:)
This is Owen with Spencer....
