Central Flying School Top Hat Trophy

[Duplo]

I'm carrying out a wee bit of research on the subject of the Top Hat Trophy and wonder if there are PPRuNers out there that can help..? The trophy is normally presented to the QFI student achieving the lowest overall pass mark during the groundschool part of the QFI course. I have the following questions:

When was this trophy first presented and why a Top Hat?

I've never been to a dinner where this award has been presented but understand the winner makes a speech and toasts the CFS. I here tales that some of these speeches have been hilarious, others have been rather 'pointed' at the CFS system or characters - can anyone elaborate with a story or two?

And finally, are there any distinguished winners of this award retired or otherwise..?

Thanks in advance.... Duplo
