An elderly couple (Pak Pandir & Mak Andeh) is getting ready for bed.
Mak Andeh says "Oh I am just so hungry for ice cream and there isn't any in the house."
Pak Pandir says, "I'll go get some".
Mak Andeh says, "Vanilla with chocolate sauce, with whipped cream on top and a cherry."
Mak Andeh adds, "Please write it down, I know you'll forget."
Pak Pandir says, "I won't forget; Vanilla with chocolate sauce, whipped cream, and a cherry."
Away he goes.
Hours later he comes back and hands Mak Andeh a paper bag. "In it is a "HAM SANDWICH".
Mak Andeh says, "I told you to write it down! You forgot the mustard."
