My best friend's oldest has a collection of logo golf balls, most of which I gave him. He has them on display in his bedroom.
His (female) cousin walked by, saw them and said, "Oh, DB, I love your balls!"
Then she turned 50 shades of red.
Once while taking a walk on the beach, I saw a guy playing "fetch" with his Lab. He had a plastic object that would retrieve the slobbery ball and toss it again. Since we had a dog at the time that slobbered all over the tennis balls we gave her, I asked him, "Can you tell me where you bought the tennis-ball retriever?"
At least that's what I hope I said, because later, I swore I remembered asking him, "Where'd you get your ball grabber?"
