[ji-] Jimmy Neutron is in the [4] bathroom of the [-e] electricity plant where he wants to go into one of the stalls. Between him and the stall is an electric 廾 fence that keeps on shooting off electric 言 words that 誡 admonish him to not cross. Jimmy, who thinks he is too smart to heed what it 誡 admonishes, goes under the electric 廾 fence. The next second an electric 戈 halberd comes dropping from the ceiling and stabs Jimmy right in the back, pinning him to the tile floor while shocking him. He should've known better. He was 誡 admonished!
