Terribly Unfunny

Ok... I see these all over Edinburgh and the protaginists are clearly overjoyed to be cheering up our otherwise dull lives with their top-drawer comedic wizardry.

This had me devise a phone call:

Unfunny Wag: Hello is that Shanks?
Shanks Man: Yes how can I help?
UW: It's regarding the defacing of the company name on your bins.
SM: Yes, go on?
UW: Well, I know how to fix the problem.
SM: (With some trepidation) Uh....yes?
UW: Change the company name to "Sharks"
SM: Thanks for calling.
