Adding R's to the end of words is a New England accent thing. It's pretty rare now and is almost exclusively old people in rural areas that still have it. Other common funny words are sar (instead of saw), pupcorn, and hutdog.
these things (in weird day-glo decoration) were all over the place in Tokyo back in 2000. I was never sure how you were supposed to get it home once you won it, since the machines sat unattended outside of arcades.
also, they were fine in the winter, but became really disgusting in the middle of summer.
