From the mouth of babes: Pon-pon!

Mummy's in car driving in KL traffic. Stupid @#$% KL driver tries to cut into Mummy's lane without signalling. Mummy immediately leans angrily on horn, cursing under her breath. Ponnnnnnnn!!!!!! goes Mummy's car horn.

From the backseat where Connor is comfortably buckled into his car seat comes a merry toddler voice in sing-song "Pon-pon! Ponponponponponpon!!! Ponnnnnnnnnnn!!!!!!!!!!!"
