I like jokes like this as I can forward them to my grandchildren who also love puns and plays on words.
I have not cared for some of the recent postings on this site but that applies to much of what currently passes as ‘humour’.
I went to the betting shop to put a tenner on aliens landing on Earth in the next year. The odds were 10,000/1, which I thought was quite good. While I was there I asked the chap behind the the counter what the odds were on Spurs winning a trophy in the next ten years.
‘I don’t know,’ he said, ‘why don’t you ask the aliens when you see them?’
