I went to the doctors with stomach ache, and he asked me what I'd been eating. I said "Today I had egg on toast for breakfast,sardines on toast for lunch and mushrooms on toast for tea".
"What about yesterday? " he asked me. "Well",I said" I had plain toast for breakfast, beans on toast for lunch and toatoes on toast for tea"
He asked how long I'd been eating this type of diet. I told him about a month.
Apparently, it's nothing to worry about - just a case of Mixing my toasties !
