有個大學生零用錢花光了，日子難熬，
想向老爸要錢，但又不好意思。
於是就寫了下篇文章：

$eptember $ixth, 1997
Dear Mom and Dad:
Gue$$ what I need? Plea$e $end $ome a$ $oon
a$ po$$ible. Thank$.
Be$t wi$he$,
Your $on $am

父母的回函更是技高一籌：
NOvember second, 1997
Dear Sam:

We have NOthing else to tell you.
Please write aNOther letter soon. Bye for NOw.
