Blue Silk Pyjamas

A man calls his wife and says to her:

- Honey, I just got the chance of a lifetime to go on a week-long fishing trip with my boss. Could you pack up my things so that they will be ready when I get home?

- Sure, honey - his wife answers.

- Oh, and could you please pack my blue silk pyjamas?

- Sure, honey - his wife answers again.

The man comes home, picks up his things and takes off for the week. He returns a week later, smiling. His wife greets him at the front door:

- So honey, how was your fishing trip?

- It was great... - the husband answers.

- But you forgot to pack my blue silk pyjamas.

- No I didn't - said his wife.

- They were in your tackle box.
