If you are planning to resign in the near future then this is an amusing way to do it.
Before you use this you may want to consider whether or not your boss has a sense of humor.
This is only important if you care what your boss thinks.
If you don't then this card is sure to amuse you and maybe your co-workers.
Let your boss know that they are losing a valuable asset ... you!
There is space on the card to write the necessary dates in order to give the notice that may be required.
If you want to add a personal message there is room for that too.
