Cool Bananas! Not one but two tippety top secret messages retrieved after work today.
First an excellent offering by QOS, entitled 'penguins vs stickmen':

I think I'll side with the pengoes: free booze and snouts? How can they lose? I was rather indiscreet with retrieving this message. I'd already used up the 'tying my shoelace' routine looking in the wrong place for it, so I just sort of pretended to squat down to rest my weary legs, but as soon as I saw the envelope all pretence was lost as I grabbed straight for it. Fortunately the only witness was a tramp, but lord knows what he thought I was up to. In my haste to retrieve the item the envelope tore, and I'm afraid I left some of the envelope as evidence - will have to send in a cleanup squad later. Actually I'm more concerned that I left two big wads of precious precious blu-tak!
Next there was the rather more puzzling offering from daisy, on the theme 'scurvy sea-ducks'. My team of experts is still struggling to decode this one.

I was a bit more cunning while retrieving this one. It was stuck behind a phone, so I picked up the reciever to pretend to make a call. Ok, as soon as I saw the message I grabbed it and hung up, but it was more subtle 'cos there was no one around. Now I just want to know what was in the lower right corner that was so secret that daisy had to cut it off? The mystery deepens.
And there is still yaggers package lying uncollected - this totally rocks!
