 ChefPoobie Sep 25, 2007 wow! thats a toughy! good one though! IQ_master Oct 08, 2007 Mr. Peter is a veeeeeeery funny man.... (: dreamlvr1432 Oct 28, 2007 great teaser, got my brain working. My only concern is for Mr. Peter and his need to wear 2 shirts everyday... scallio Dec 11, 2007 Great teaser! Took me a while to realize I was going to have to have either black or blue on Wed, Fri and Sun in order to avoid having the 4-day color next to a day of same color. I recognized one color would be 4 days, 2 colors would be 3 days and 2 colors would be 2 days and still had a hard time realizing that. Once I got over that hump, it was all downhill. Thanks for a fun morning! 7mi27 Jul 02, 2008 HAHA!! Peter NEEDS to get over his weird habits! But thanks for sharing!!!
