1 {A post-it note, with the following items written on it in an old-fashioned cursive hand:}
1 [note]: - Milk
1 [note]: - Bread
1 [note]: - Eggs
1 [note]: - Toilet Paper
1 [note]: - Flowers for Mrs Fermat
1 [note]: - Pay Phone Bill
1 [note]: - Write out that Proof
1 [note]: - Cat Litter - URGENT!
1 [note]: - More Post-Its
1 [note]: - Writing Paper
1 {in the top right of the note, with an arrow pointing at the last two items in the list} why is there never anything to write on around here??
1 {bottom right, squeezed in the remaining space in tiny script} I found an odd perfect number but it's too long to write here

And here we have Fermat's Last Post-it.

I've talked about Fermat's Last Theorem before, so al I need to do here is provide the appropriate link.
