Did everyone know this about the original wisc

So I was just listing to the reborn version and I tapped on the lyrics and I noticed at the end there was (she's a lair she's a lair she's a lair) now I also didn't know about the mother fucker near the end as well until I listened to the reborn version, I had a listen to the original and it's very faint but you can hear Cody go she's a lair she's a lair she a lair with a small break in the last lair and just that's so cool, how did I never notice that, like that's such an old sio thing and it's so cool to hear them keep little things like that in the reborn version!!
