I KNOW WHAT I SAW

Due to my popularity, many have been calling me.  State Farm, Tuna, and an individual whose initial is S.   And I kept seeing 'WIRELESS CALLER."       I called Tuna.  That was important.  Tuna doesn't like to talk on the phone, and so after that I called "S".  Nothing.  Then I looked for the wireless caller.   No wireless caller.  This is just weird.
