These puzzles are waaay beyond me.
I sometimes try cryptic crosswords but at least there's a clue in the number of letters in the words and once you get a start it gets easier.
This is a good one to try on your mates that I picked up from a t.v programme.
Ask them to recite 50 different words in 20 seconds that don't contain the letter "a"
I assure you it is possible and they're all words we all know.
I liked this - hadn't seen this type of puzzle before.
One thing threw me, which is that there should have been five dashes for the final word (I kept adding up the dashes to get 29, yet there were 30 letters!).
Thanks for posting. Looking forward to the next one.
