Normally, about this time on Mondays, my advice to you would be to start drinking heavily.
And you ought to listen to me. I've been to a doctor.
Sometimes, unfortunately, drinking heavily isn't a Monday-night option -- namely, because you used up the last of your booze Saturday night. Well, in that case, I recommend this bit from a 1990 episode of A Bit of Fry and Laurie -- Stephen Fry and Hugh Laurie -- on BBC2.
It'll make it all better. I promise.
