Freddy beat me to it, but yeah, they'd be the ones in the center of his picture. Those two jumbo-sized ones on the ends make them look small (they're definitely not). I think the cardboard tube from a roll of paper towels is probably close, though maybe not as big around.
Point being, if you take one of those, or something cylindrical and that size, and hold it where your dick is, you can easily see the resemblance to a Dingo dick, and as I mentioned, it looks really ridiculous. The idea that everybody in here, or their BF/husband, is the size of (or even an inch or two bigger than) a guy who was made world famous for the size of his penis, the likes of which hadn't appeared on the porn scene until circa Y2K and to this day is pretty much unrivaled there, is absurd.
