Your dogs sound very entertaining, I've got some good ones too about my 2 golden retriever mixes.

Upon entering the house, they always circle the couch completely at least once at full speed (it's right by the back door) even though there's plenty of room to get around it.

When the grass in the backyard is high, one of them will not go out into it to "go potty." She will go right next to the deck. Evidently she doesn't like the tickling feeling on her legs!

The same dog once had ants in her food bowl outside, so we moved it inside. She does not eat until she has pushed the food bowl all around the kitchen with her nose, and she throws food out of the bowl with her nose to check for ants.

They are both terrified by any toy that squeaks. The big dog will actually growl at the toy.

Have a great day!
