Taco Jack 

An amazing creation from the Value Menu at Jack In The Box. You start with Breakfast Jack and the 2 Regular Tacos, each 99 cents. You split the Breakfast Jack between the ham and the egg and insert one of the tacos, adding taco sauce if necessary. Slap the Bfast Jack back together and enjoy that tasty 'wich!

Greg: Breakfast time!

Friend: Is that-did you put a taco in a breakfast sandwich?

Greg: Fool, this is a Taco Jack...get outta my face!
