Wan't it a Peter Kaye joke originally.
Reminds me of the time I was in Pizza Hut when Wayne Rooney came in and sat at the next table. He ordered a pizza and the waitress asked if he would like it cut into 4 or 8 slices. "Four", he replied, "I don't think I could manage 8."
Which reminds me of the time Wayne Rooney was in Debenhams looking for a present for Coleen. He came across a display where a young attendent was demonstarting thermos flasks. Amused, he asked the attendent to explain what the flask actually did. "Well", she said, "you can put hot things in, and they stay hot"
"Wow", said Wayne.
"but you can also put cold things in and they will stay cold", she added. Amazed, Wayne bought one.
Upon arriving home, Coleen rushed to the door,
"Hello Wayne, what have you bought me today?" she giggled.
"This flask, its great" he said.
"What does it do?"she wondered.
"you can put hot things in it and they stay hot"
"Wow" she said.
"And you can put cold things in and they stay cold" he added.
"Double wow" she said excitedly.
"Theres more" he added, " I've filled it for you. Inside theres some ice cream and two cups of coffee."
