Mine has to be from Cecil B Demille's 1949 adaption of Samson and Delilah.

Samson(Victor Mature) has just wrestled with and killed a young lion with his bare hands right in front of the adoring Delilah (Hedy Lamarr).

She rushes over to him and cries

"Shamson Shamson, I love you, I would kiss you wis my dying breath"

Victor's brushes her aside with a smirk and says.

" Hey one cat at a time".

quite DeMillian really.
