This week on Thinking Thursday were going to look at one of the most famous riddles of all time, and see if you can come up with an answer.
The riddle I pose is one originally penned by Lewis Carroll in Alice in Wonderland:

As always there is no prize except the fun of the chase but if you wish to put your answer in the comments I’d love to read it.
Answer on Sunday evening, as usual.
Oh and no cheating on this one by looking it up on the intertubes. ☺
