How about Wendy's French Fries dipped in a Frostie......
Our youngest has to have ketchup mixed into his gravy....

It was really gross when the ketchup use to come in colors....that was really weird....
All our kids eat Pizza with Ranch...They think it is the only way to eat it....Apparently, lots of people eat it like that- our Pizza Inn nows serves Ranch to go with the pizzas...Go figure...
My personal fav is fried jalapeno slices....then dip in ranch.....
