Be Careful In English Pubs
Old man came in, took a pinch of snuff, sniffed and thought "funny, I can smell dog shit". He checked his shoes, looked around but couldnt see any he had trodden in.
Next old guy came in and the 1st man said "Hi Harry, can you smell dog shit ?"
"No" repled Harry, taking a pinch of snuff.
"Bloody hel_l" he said, "this snuff must be good, I can smell it now!"
