Prayer to St. Anthony, Patron of Lost Items

St. Anthony, grant that I may find (name the lost item) which has been lost.  At least restore to me peace and tranquility of mind, the loss of which has afflicted me even more than my material loss.[1]

You can also say:

Tony, Tony,
look around.
Something's lost
and must be found!

You can also substitute the name of the article you're looking for (e.g., my car keys) for the word 'Something.' [2]

..or simply, "Hey Tony! Where are my keys!"
