For me, it was "Horrors of the Black Museum".
My cousin took me when I was like 8 or 9 yrs old and the first scene where this lady receives a present in the mail and it's a pair of binoculars. So she goes over to the window to use them and these 12" knives come out of the eye peices and shes got her hands on her face with blood POURING out between her fingers and shes' screaming........
Man, you never saw a kid run out of the theatre so fast
