Harsher in Hindsight:
- Bassist Roy Estrada messing around with the inflatable sex doll in Baby Snakes wasn't quite as funny after Estrada was arrested and convicted for child molestation in 1994 and 2012.
- Quite some lyrics or song titles in Zappa's oeuvre refer to STD's, which were a nuisance in the 1960s and 1970s, but back then all medically treatable. Since the arrival of AIDS in the 1980s references as such don't sit so well with modern day listeners. Especially considering Lucy Offerall, one of the groupies in Two Hundred Motels, died from it in 1991.
- While it's a pretty safe bet that the 9/11 attacks weren't what Zappa had in mind, this line from the "Hydrogen" section of the chapter "All About Schmucks" in The Real Frank Zappa Book reads much differently today.
"Some people in the Imaginary Heartland of America might say,Who gives a shit? They ain't going to get us. They ain't coming over here. Why, some of 'em don't even have air-o-planes."
