Teen Titans Go #45 (2007)

The story begins with Beast Boy, Cyborg, Sarah Simms, and several children sitting around a campfire at night. Beast Boy decides to entertain the kids with his "secret origin story." He begins by saying that he was with his cryptozoologist parents hunting the chupacabra in the jungles of Africa. Cyborg interrupts telling the kids that Beast Boy's parents were biologists, not cryptozoologists. Beast Boy is obviously changing some details to make his story more interesting. When Beast Boy yells at Cyborg to let him continue, the children begin asking questions on why they were looking for the chupacabra in Africa when it is really native to South America. Beast Boy realizes he's about to be caught in his lie so he changes his story again. This time, Beast Boy says that he was with his parents in the Mesa. He explains that he got lost and was attacked by a basilisk. The basilisk, instead of turning him to stone, transformed him into what he is today. Cyborg interrupts again, calling his bluff. Cyborg tells the real story of how Beast Boy got his powers. Cyborg tells the children that Beast Boy was bitten by a green monkey in the jungle and his parents gave him an untested antidote that allowed him to transform into any animal at will. As Cyborg begins arguing with one of the children, Beast Boy talks to Sarah Simm about his parents. He explains how there was a flood and his parents died. He says that he wasn't an orphan for long though. He was soon recruited by the Justice League! Cyborg interrupts again and, again, calls out his lie and says that Beast Boy never joined the Justice League. Cyborg then begins to make up lies himself saying that the Doom Patrol found Beast Boy at the pound. Beast Boy defends himself by explaining that he wanted to join the Doom Patrol and broke into their base. After a short fight, they were impressed and adopted him. The children are skeptical about that part and go to sleep. The irony is that Beast Boy was actually telling the truth about that part. The boys head for their tents, making up their own origins for Beast Boy. Beast Boy is mad that the kids don't believe him and he mutters to himself as the story ends.
