Note: the expression ketchup and eggs comes innocently enough via Commatology, in reference to red and yellow tulips. Cute. Except for this: despite having no interest in ketchup at breakfast, I can no longer see yellow and red without thinking of defiled eggs.
So [ahem]… gee thanks, Leslie… this one’s for you!

Sorry about that, Carin! (she says with a devilish grin) I think it’s the lack of interest in ketchup at breakfast that causes one to see the combo everywhere. It’s something akin to the tongue seeking out the aching tooth.
I love your colour posts and look forward to seeing what’s next.

Well put!
