Paddy and Mick on holiday is Austria when Paddy sees people skiing down a mountain.
"Just look at those skiiers zag-zigging down that mountain over there!"
"It sure looks fun Paddy, so it does", replied Mick, "but the correct term is 'zig-zagging'".
"No, no, no Mick!", Paddy insisted. "It's 'zag-zigging'. Skiiers always say it so they do. 'zag-zig here', 'zag-zig there', 'zag-zig' everywhere!"
"Paddy, you're wrong so you are but I tell you what, why don't you ask that bloke over there?"
So paddy walks over and asks, "excuse me sir. My friend and me are having a slight disagreement so we are. Would you say those skiers over there are zag-zigging or zig-zagging down the mountain?"
"I've no idea, sorry", replied the man, "I'm a tobogganist".
"O!" Paddy exclaimed, "well in that case I'll have 20 Bensons!".
