Dah Doh
My nephew was obsessed with planes, trains, and automobiles at the time. His favorite book was called Things That Go, but he pronounced it "Dah-Doh!" For Christmas, I recreated the book cover with his pronounciation and replaced all of the characters with family members and had it printed on a pillow.
