People with a strange idea of fun might like to cover themselves in mayonnaise and wrestle. Perhaps they prefer to cover their bodies in ketchup and mustard instead. Personally, I only like to put mayonnaise on my sandwiches or with my tuna. :D

People like to put ketchup, mustard, and mayonnaise (or mayo) on their meats and with starchy things like french fries (or any other fried potato food). It's not too common for people to put mayo on salad, but some do. For sandwiches with cold meat, people tend to only use mayo and mustard. Or at least in the part of the USA that I come from. I personally like all three, although I don't always like the sweet, tangy ketchup.

I use ketchup on hotdogs. I just love the taste of ketchup. It's just so sweet and tasty. Whenever I have food that needs ketchup I tend to use a lot. I used to use mustard too when I was little but now I just can't stand the taste. Mustard just tastes bad. It's so sour. I can't even remember the last time I had mustard. The only time I use mayonnaise is for sandwiches. I spread mayonnaise on some bread then put slices of cheese and ham between them. Then I chow down! I love mayonnaise! Mayonnaise makes this type of sandwich taste much better. A ham and cheese sandwich just isn't the same without mayonnaise.
