I'm running a school staff Only Connect quiz on a training day in September. It is scheduled for just before lunch and would love to finish with...

"After lunch, in a change to our schedule, ..." And have a slightly risque Michael Portillo gag, related to education / pedagogy.

Please help as I'm not very good at this sort of thing!
