We just love the Big Bang Theory and have fallen in love with Sheldon's bed time song "Soft Kitty".  My daughter saw this shirt while on Amazon and asked for it for Christmas.  It is baby-doll cut and made of very soft cotten so "soft kitty" goes well on it.  She just loves it and it has been washed a number of times with no fading of the letters.  Great product and will buy again if necessary.
