I don't really see it in the same league as Carry On. Carry On was as broad as humor can get and cartoonish.
You have to laugh at the insults that the husband and grandmother trade.
Janine Duvitski is perfect as the swinger wife. And Kenny Ireland just acts like the swinger husband is the norm.
***Spoiler alert ahead***
And you got to laugh at the woman trapped in the pool because of the floating piece of crap and the wife just yelling "Oh pick it up. My husband bought it at a joke shop." The mistaken assumption is hilarious.
If anyone ever tells you that you put too much Parmesan cheese on your pasta, stop talking to them. You don't need that kind of negativity in your life.
