If it's true that white Christians like Sunday dinner, then it only stands to reason that white Christians like Sunday dinner's friendly neighbor: the Sunday afternoon nap.
While many people only truly experience the food-induced sleep-coma around Thanksgiving, White Christians enjoy this experience on a weekly basis. Nothing stimulates the white Christian's sleep-ogens like the starches, complex carbohydrates, and tryptophan of the stereotypical white Christian Sunday dinner.
After the sleep-ogens have been fully induced (this metabolic process typically occurs simultaneously with the post-meal devotions) the white Christian stumbles to the couch or the nearest padded horizontal surface like a bear that has been recently shot by a tranquilizer dart. The sedative is all the more effective when combined with two crucial nap catalysts: a moderately entertaining (but not exciting... remember, we're going for sleep here, not entertainment) sporting event on TV (such as a non-Tiger golf tournament), and an afghan.
Every white Christian enjoys napping under a gloriously warm afghan that their great aunt (or other elderly relative) knitted for them. The afghan is one of few white Christian staples that has stood the test of time. White Christians can't seem to agree on worship styles, doctrine, or denominations, but they've stayed true to the afghan for centuries. White Christians like to look to afghan for inspiration: all different colors and patterns have been woven together to serve a common, glorious purpose... it truly is a blanket of unity.
