On Thursdays I am a man of my word

[venta]

Spot question for the day:

Without googling, does the following phrase mean anything to anybody ?

Now is the time for all good men to come to the aid of the party.

There's definitely a Peanuts cartoon where Snoopy says "Now is the time for all good dogs [etc]" - this makes me suspect that the phrase is American.
