"On the 30th of month, you shouldn't be short of.... electricity" - USEK student Yves Nasr came up with this in one of the courses, the lovely bit was to first create the alarm that it is the "end of the month" only to reveal that the whole point is to have one electricity bill instead of two (one for the government and one for the private generator). Bonus points that the word "to2ta3" (short of) is also used to say "power shortage". An addition layer for the meaning? The same word is also used to speak of the period at the end of the month for women! I love how all of these intersect.
