Has Environment Minister Carwyn Jones got a photographic memory?
He has just recited his route to a quarry in Wrexham in astonishing detail to prove to Plaid AM Janet Ryder that he had been there, eliciting a round of applause from the Labour benches.
Perhaps it was one of those "you had to be there moments", but it was quite the most bizarre episode I have seen in the Assembly.
Meanwhile the below mentioned row between Dafydd El and John Marek spilled over into the chamber in what was quite the most embarrassing episode I've seen in the Assembly.
But both episodes are outdone in both regards by what I'm told happened in the Commons today - Jack Straw mime-hugging a hoodie.
