Whose idea was this?

Patterns on toilet paper?    I wonder if there's any research on the effectiveness of plain toilet paper vs patterned toilet paper.
Another idea for White.
It's our wonderful older granddaughter's 21st birthday today, so I've added 3 extras of her.  She's loved horses since she was a little girl and is happily working in a barn now.  Her boyfriend Dan bought tickets to Cavalia for her birthday - when we talked to her this morning on FaceTime, she was so excited to be going to it!  Just home from working at a horse show in California yesterday and off to Hawaii tomorrow.  Life is good!  Happy Birthday, Krista! 
1st extra:  feeding the horse with Gramps
2nd:  riding Layla
3rd:  a kiss from Dan at Ruby's beach
