Doogie makes a journal entry in the beginning of the episode.
"Date: September 21, 1989
Today is my 16th birthday. A major milestone because my driver's license is at long last a reality. Wich means tomorrow, Sept. 22, I'll be behind the wheel on the way to the Harvest Dance with Wanda Plenn, the prettiest most beautiful girl in the whole world."
Vinnie: We're out in the parking lot progressing nice then boom, deja vu, Susie Berlutti.
Doogie: You puked?
Vinnie: Right down the front of her dress. She's in the bathroom cleaning up.
Vinnie: Oh, I was just visiting with Doogie, Dr. Howser, listening to his plan to part Wanda Plenn's pulsating red lips with his probing pubescent tongue.
The German episode title is "Sein 16. Geburtstag", meaning "His 16th Birthday".
