[R] Overlay PDF on histogram

I thought that I had read somewhere that there was a really simple
way to overlay the probability density function of a normal
distribution over a histogram, after the histogram has already been
plotted. Possibly a one word command.
I've found this email from the archives, but I don't think this is
what I'm looking for. I thought there was something more simple than
the curve function.
R> x <- rnorm(100)
R> hist(x, freq = FALSE)
R> curve(dnorm, col = 2, add = TRUE)
Is there a simple way to do this, or is my memory failing me? Thank
