It's been common knowledge for some time now that whoever manages the social media for An Garda Siochana isn't shy about throwing out a Simpsons reference when required.

Back in 2015, as part of spreading the message of fighting driver fatigue, they sent out the below tweet about having some coffee or even a doughnut during breaks.

And they weren't shy about throwing out a classic reference to Chief Wiggum in the replies. 

Well now they're at it again. The Facebook Page for the Garda Síochána - Cork, Kerry & Limerick - Southern Region posted the below image that was spotted on the roads recently. As they mention in the caption, the sign features a bit of 'wanton vandalism' . The sign is brilliant but the caption that goes with it more than matched it. 

In case you missed that episode, here's the scene they're referencing. 

That's some good Simpsons referencing Lou. You'll make Sargent for this.
