Dare to be stupid

Engage phase 1 of Operation DoubleMint. Don't spend all of your $2 bills in one place, but spend enough to get a reaction!

Should we put the secret symbol on the $2 bills before we spend them?

Roger, WILCO.

Certainly, use secret symbol seventy-six sigma

That was a decoy secret symbol; look on page 753.2b#56 of your manual for the super secret symbol.

Our Australian chapter really must update THE MANUAL
We got rid of $2 notes quite a few years ago. Only a coin now.
I did study the coin with my "secret" super power magnifying device,
but couldn't detect the symbol.
Well done our member in the Royal Australian Mint.

We'll have better results with three dollar bills.

True, but the ink is still wet. Give it another few hours. The seven and a half dollar bills are dry, though!

Exchanges secret Aussi handshake with WillSteed (...of course you know it,it's the one with the blue ring octopus, 3 tinnies and the vinegar...)
Are the denominations still 12 pinecones = 1 clam, 20 clams = 1 platypus?

And, of course, 7 platypi = 1 inflatable rhinoceros.

platypodes

I sit corrected.

Or as the platypuses,pytypi etc. call each other...
Hey Fred, how'r you goin?

#11 -- So, when I'm paying my club dues, how many months does an inflatable rhinoceros get me?

Enough to last until we can't remember when they're due.

Excellent.

Don't forget that 14 inflatable rhinoceri = 1 rubber baby buggy bumper.

Oddly enough, 6 rubber baby buggy bumpers = 1 pine cone

Yeah, but it's a pine cone from a bristlecone pine.
