All I really remember was there was a hispanic guy who would molest cooked turkeys, frogs, and chickens. For example, he used a banana to "hump" a turkey, and a french fry to "hump" a frog.
Solved! Dad remembered it, believe it or not.
It's The Whoopee Boys (1986)
Here's one of the scenes I remembered. The Hispanic guy doing perverted things to the cooked frog (or hen, or whatever it is) is at about 3:34.
