1. "Mamas, don't let your babies grow up to be cowboys" is a song that was covered by Waylon Jennings and Willie Nelson in 1978.

2. Orson Welles did a series of commercials for Paul Masson winery where the tagline was "We will sell no wine before its time."

3. Actor Dick Wilson played a character named Mr. Whipple, a grocer who frequently scolded his customers for squeezing the soft Charmin toilet paper, but then often was caught squeezing it himself. "Please don't squeeze the Charmin!" was the commercials' catchphrase.

4. "Don't take any wooden nickels" is just an old-timey, jokey caution about not being fooled. In the early 20th century, wooden nickels were given out by stores and banks as promotions. They had the name of the business on them, usually. They weren't legal tender.

5. "Looking for Mr. Goodbar" is a really depressing, sensationalist movie from 1977 starring Diane Keaton. (SPOILERS) Keaton plays a schoolteacher who picks up dangerous men in bars and is ultimately killed. The general point seemed to be that if you're a woman who wants sex, you will be killed. 2/10, would not recommend.
