Afs, you know me far too well!
I didn't realize those actors were from the Downton Abbey show since I don't watch that one, but it was funny regardless getting to see a prim and proper Walt as a tea kingpin.
Well, I'm guilty of watching that bloody(!) show as well.
And since all of them are Brits, I was really surprised how Colbert had arranged for all that. But he is the sort of guy you don't say no to.
Anyway, I instantly was thinking of you when I watched that, since you are a fan of both, just as I am.
