A new problem for the embattled retailer .
Reddit users noticed the "Hitler tea kettle" on a highway billboard near Culver City, California.
And once you envisage Adolf doing the "I'm a Little Teapot" dance, you really can't unsee it. The offending kettle is also for sale on J.C. Penney's website. As yet no online shoppers seem to have noticed the similarity, instead describing it as "gorgeous and shiny" or "functional art."
