keep it under one's hat 

Keep something a secret.

There are four origins of this idiom (I GUARANTEE IT):

- English archers protected their bows by putting the strings on their heads under their helmets;
- “keep it under our hat” was mentioned in 1982 in periodical "Gleanings in Bee Culture";
- President Abraham Lincoln's stove pipe hat, where he kept important papers;
- the ceremonial swordbearer of the Lord Mayor of London (can be dated to 1420), who keeps the key to the Lord Mayor’s seal of office in a special pocket in his hat.

-keep it under one's hat-

Joey: All right, what else?

Joey: Which we're still keeping under our hats!
