One particular episode made use of the phrase, "A stranger is a friend you have not met yet", which some parents may view as sending a dangerous message to their children. Another episode was criticized because a situation in the episode could be interpreted as teaching children that cheating is good. In the episode, the children are involved in a contest where they have to carry a spoon with a peanut on it without dropping it. One child wins by putting peanut butter on his spoon to make the peanut stick, and then he is rewarded for "creative thinking." Another episode was also criticized because one situation could be interpreted as teaching children that it is okay to steal. In the episode, one child steals cookies from another child, but the other doesn`t care because he didn`t want them in the first place.
Critics have alleged that the show condones peer pressure and "group think", saying it encourages children to suppress outward signs of unhappiness rather than deal openly with their feelings, which has been shown to have dangerous effects on their development. This has also led critics to believe Barney is an attack on individualism. The most popular claim is that many believe the children all act alike, and never express unique traits, likes, dislikes, or feelings.
Many individuals have been associated with the Number of the Beast (666) using a variety of schemes to transform their names or mottoes into the infamous number. One of the most widely-distributed works of Anti-Barney humour provides a 666 calculation for the character of Barney as follows:
1. Barney is well-described with the following phrase:
CUTE PURPLE DINOSAUR
2. The old Latin alphabet used the letter 'V' in place of 'U', therefore the above phrase is modified to:
CVTE PVRPLE DINOSAVR
3. Letters that do not represent Roman numerals are removed:
CV-- -V--L- DI----V-
4. Add up the Roman numerals of the remaining letters:
C + V + V + L + D + I + V
100 + 5 + 5 + 50 + 500 + 1 + 5 = 666, which is the Number of the Beast.
5. Therefore, Barney is considered Satan.
