Yes, take it back -OR- I agree with Suzanne's suggestion, only use it when your father is there. Make a nice (nice???

) little deep-fried dish and have VERY LITTLE of it. Then when dad leaves, put it back away until he visits again.
I'm not personally saying that I
never eat anything deep-fried. But it's extremely rare when I do and it's usually stealing a couple of fries from someone or a chicken nugget or two once every so many months. Except for the very rare little snickie snack, I stopped eating fried foods 2 years ago. And I certainly don't want a mechanism in my house designed specifically to take a perfectly healthy food and turn it into a nutritional nightmare
I have a deep-fryer. It's been gathering cobwebs since June of 2004.
