A colleague brought a cake to work. After drinking I asked:

What is the reason?

He stretches his hand with a bright manicure.

I think, oh, now in honor of the new manicure cake is already wearing. I say sarcastically:

The reason, of course, is significant.

Then a colleague switches to a conversation with another person and from the conversation I understand that she showed a wedding ring on her finger, not a manicure. It was uncomfortable, but the phrase almost fit into the conversation.
