The Bad Idea Bears are two characters in Avenue Q. One is the colour blue, is male and wears a bow tie around his neck. The other is the colour yellow, is female and wears a bow on her head, a necklace around her neck and a dress.
Their first appearance is when Princeton is closer to finding his purpose in life, shortly after the song "Everyone's A Little Bit Racist" They find him and convince him to waste his parent's money on beer, occasionally crying when he says "no" and yelling "YAAAAAY!" when he finally accepts their suggestion. Later, whilst Princeton and Kate Monster are bonding in a café, they come to him with some Iced Teas and persuade him to try a "drinking game" which results in Kate getting completely drunk. In Act Two, they attempt to make Princeton hang himself, and this does not work.
At the end of the musical, they seem to have learnt the errors of their ways by discovering Scientology.
