Not in Ireland because we just call it mayonnaise, but I posted a thread here once with 'Mayo' in the title - 100+ posts, mostly jokes!! I wouldn't mind, but it was a serious story, thankfully Tax-Chick posted the first serious reply on the thread!! (Remember that thread, Tax?)
Yes, it was about the farmer who shot the "tinker" on his property, wasn't it? You have to admit that "mayo farmer" was a bit provocative :-).
