I sign the words "purple monkey dishwasher" on every note I enter, in case you find any. Keep your eyes peeled.
Actually this is why I usually enter notes in smaller batches, so I don't get suckered into entering 100 notes where like 90% are repeat entries. BELIEVE IT OR NOT, this has already happened to me.... the one bank shipped over their batch of 100s, and I picked them up at another branch a few days later. Sick!
I hope you know I am joking about the purple monkey dishwasher signing, although I have used that phrase in some beautiful opportune times for some good times.
