Webster's vs. OED

Mom...

Yes?

How do you spell "favourite"?

F...A...V...O...

[hesitant pause]

And then?

[defeated sigh]

R...I...T...E....

(Can I claim the When in Rome defense? Or mollify you with protestations that he is already having to learn how to spell in both English and French and to throw in a dialect form of English is possibly a bit much for the second grade?

Yeah...it doesn't fly with me either.)
