K-Mart Liturgy
You get up on a Sunday morning, take a shower, dress, then head out of the house. Your family is very sure that you are a good boy, heading out to go to church. Instead of attending church services, however, you go to K-Mart and spend just the appropriate amount of time there browsing merchandise so upon your return, your ruse is very convincing.
Frank's parents think he is such a good boy but we know the truth. He did a K-Mart Liturgy and bought condoms.
