This was taken on June 14, 2009 along Commonwealth Avenue, and it still cracks me up to this day. This is how I imagine the meeting went:

Head: Dapat may nakalagay diyan na flashing arrow para alam ng mga motorista na may ginagawa sa lugar na yan.
Staff: Sige po, kami na ang bahala.
Head: Tandaan niyo ha? Flashing arrow ang ilalagay diyan.

And this is how I imagine the succeeding conversation went:

Staff: Napalagyan na po namin ng flashing arrow yung sa may Commonwealth, gaya po ng sinabi niyo. Puntahan po natin.
Head: *miffed silence upon seeing the sign*
Staff: Okay po ba?
Head: *trembling violently* Mga bobo! Hindi ko sinabing magpaprint kayo ng tarp na may nakasulat na “flashing arrow”! Eto ang ibig kong sabihin!! *head shows the staff a picture of the intended flashing arrow*
Staff: *headscratching as one*

As I recall, it was taken down several days later and replaced with an actual illuminated, flashing arrow.
