The moral of this story......if the king wants to drink donkey piss, give the king donkey piss.

Nothing beats the old Molson Canadian ads.

Yeah, I'll take the wine thanks.

And I don't drink wine.

Whenever I see these ads, I can't change the channel fast enough. The dilly just grates on me.

Is Bud Light really good enough for this joke?

WTF does Dilly Dilly mean?

More often than not it's just used as a nonsense word. See this 17C example for instance:

Lavender's blue, dilly dilly, lavender's green,
When I am king, dilly dilly, you shall be queen:
Who told you so, dilly dilly, who told you so?
'Twas mine own heart, dilly dilly, that told me so.
Call up your men, dilly dilly, set them to work,
Some with a rake, dilly dilly, some with a fork;
Some to make hay, dilly dilly, some to thresh corn,
Whilst you and I, dilly dilly, keep ourselves warm.

If you should die, dilly dilly, as it may hap,
You shall be buried, dilly dilly, under the tap;
Who told you so, dilly dilly, pray tell me why?
That you might drink, dilly dilly, when you are dry.
