The scene I remember involved US or British troops hiding on the side of a road (possibly bridge). Germans were advancing (I believe tanks) and one of the allies went out on the road, put nitroglycerine on a dog dropping and ran back into hiding.

The vehicle rolled over it and exploded.

The quote I remember was something along the lines of "now that's some super duper doggie doo!"

I think it was a black and white movie. Would be the kind shown on TV once or twice a year.

Thanks in advance.

Force 10 from Navarone comes to mind. It wasn't in black and white though.

Force 10 from Navarone

it was plastic explosive shaped like canine softserve....and yes, Force 10

Thanks guys, I will see if I can't isolate the clip to verify, but it sounds like you're both spot on.

Maybe all we had was a black and white TV, it has been years since then.
