Jars

There are quite some Zappa songs that reference jars:

• Sleeping In A Jar
• Let's Make The Water Turn Black (Not mentioned, but implied. We know from Ronnie's Booger Story and Kenny's Booger Story that they stashed away their urine in a large jar.)
• The Idiot Bastard Son ("Kenny will stash him away in a jar.")
• God Bless America ("the old cookie jar")
• Tiny Sick Tears (Again a cookie jar is mentioned)

You tiptoe through the living room to the kitchen to find the cookie jar – your favorite oral gratification: oatmeal raisin cookies! They're in the Aunt Jemima cookie jar. You rip her head off and stuff your sweaty teenage hand into her body. You grab a cookie – tempting raisins, a fascinating tactile sensation – you know you're gonna get off on it. You go to the icebox, open the door, take out a box of milk and pour it into your drinking hole."
