I was looking at the "goofs" for Horses' Collars, and there are one or two goofs that weren't picked up...
1) The scene where the Stooges walk in to the dancehall where Nell is sitting. The Stooges bow down to Nell, Moe bops Curly on the head...when they recover, Nell says, "Oh gentlemen..." Moe is looking at Larry, then all of a sudden, all 3 look at the camera as if something went wrong...then Moe motions to Curly...then the scene cuts to them turning around to see who came in.
2) When Curly beats up the 2 thugs at the end...Moe and Larry come in tied up...Curly punches them both while yelling, "Moe Larry, the cheese." Moe gets untied, and slaps Curly on the head...when Curly falls backwards and roles over on his head, sand comes trickling out of Curly's belt or holster.
