Barbeques on the beach are great - just make sure you're grilling hotdogs, not a pair of legs that look just like them!

A new tumblr has sprung up with photos of people's legs on the beach, in their backyard, sometimes in the kitchen, but always having a great time. Or are they hot dogs? That is the question. It's amazing how similar a pair of hot dogs look to a pair of legs when they're reclined on a towel.

It gets even harder to tell them apart when their setting is a natural habitat for both! Who knows what you're looking at when the two fleshy-looking brown things at the bottom of the picture are in front of a grill or next to the pool.

See if you can tell if these photos are of hot dogs, or legs!
