The Flight of the Firefly - S1.E61

While looking for fireflies in the backyard, Hal catches one so the gang can look closely at it and watch it glow. Hal names the firefly George and promises to watch it and hug it and then set it free which he does, but for some reason George doesn't want to fly away and hangs around Hal. George seems to have something on his mind. Since no one can communicate with a firefly, they call in Houston. With the help of his firefly communicator, they find out that George is lost and needs help finding the Firefly Fiesta!
