One particularly infamous lyric in PaRappa the Rapper is in Prince Fleaswallow's rap, where he claims to have "been working here since [his] mama was a baby". While it is simply an exaggerated simile and not an actual piece of world lore, it has still been the source of mild chuckles from players for its unintentionally disturbing undertones if taken literally.

When music from PaRappa the Rapper was played by an orchestra at Sony's 23rd Game Symphony Japan concert in 2018, the lyric would be revised from "Since my mama was a baby" to "Since your mama was a baby", a more fitting lyric as PaRappa is supposed to be a young adult and Fleaswallow is presumably significantly older.
