Pablo,
Please find attached a signed potato. (Don't ask how I attached it; faith and ZIP compression.)
File name: POTATO.EXE
What it does:
- Opens a terminal and types: "I am a potato"
- Closes the terminal politely
If your antivirus complains, tell it this is a certified tuber.
Digital signature: applied with a fork.
P.S.: Do not run while hungry.
Agriculturally yours,
Zé das Couves
