Feliz Say What?

So I'm playing a game of darts at the Park Pub with my friend Mose on the Eve of Xmas Eve and the jukebox plays the song "Feliz Navidad," but it's not the typical Julio Feliciano version, and when the singer sings the eponymous opening I distinctly hear him say "Feliz s*ck my c*ck," which totally throws off my throw and I turn to Mose and he's laughing and I say: "Did you just hear that?" and Mose confirms that he heard the same festive invitation to fellatio that I heard, but upon further investigation it might have been some weird acoustical anomaly-- that when this particular song is played on the jukebox and you're standing near the dart-board at the Park Pub and certain shows are on the television and the bar is packed to a certain density, then that's what you hear . . . or maybe it was an Eve of Xmas Eve Miracle . . . either way, I'm certainly glad Mose was there to corroborate the incident, because when we went and sat down with the rest of the group at the bar and asked them if they heard what we heard, they looked at us like we were crazy.
