Kyle's adopted Canadian brother, Ike, is to be circumcised. In an effort to protect Ike's "fireman," the boys stick him on a train to Nebraska. Meanwhile, Mr. Mackey is fired for exposing the children to marijuana in an attempt to teach them that "drugs are bad, m'kay." After a drug-induced trip to hippieville, Mackey enters rehab and gets his job back. Meanwhile, the boys learn that the point of circumcision is actually to make the pee-pee look bigger, so they happily bring Ike back from Nebraska.
