Kiell's multi-level sneaky signature

Here's a brief description of the contestant's attempt. Someone's probably working writing up more detail!

Kiell brought in a pen which he got Greg to sign a piece of paper saying "Well done for your five points", telling Greg that it was for someone named 'Tseikna Engsith', for doing well on a test. It was then revealed that the pen Greg used was a spy pen and had recorded Greg reading the sentence out loud. It was also revealed that 'Tseikna Engsith' is an anagram of 'Sneakiest thing'. He received 5 points.
