One of the funniest guys on late-night TV, Jimmy Kimmel stars in another witty skit at the Jimmy Kimmel Live show, which features a child being interrogated with a lie detector test.

In the skit, the cute 7 year-old gets in trouble for dodging Kimmel’s questions. When asked if he likes school, he answered “yes” and got buzzed by the machine for lying. In another scene, Kimmel asked the child if he ever peed in the swimming pool. The boy paused for a few seconds before answering “no,” which got him buzzed again. Kimmel’s accomplice, the Truth Fairy, then prompts the boy by admitting that he himself peed in the swimming pool.

Take a peek at the clip below.
