Open Up and Say... Ahh! is the second studio album by American glam metal band Poison, released in 1988 through Enigma Records. It proved to be the band's most successful release, and spawned four hit singles: "Nothin' but a Good Time", "Fallen Angel", "Your Mama Don't Dance" (a Loggins and Messina cover) and their only #1 single to date, "Every Rose Has Its Thorn". It peaked at #2 on the US Billboard 200, being denied the top spot by Bon Jovi's massively popular New Jersey album, Guns N' Roses' debut record, Appetite for Destruction and Def Leppard's most successful album, Hysteria.
