If you're in Syria and a Mark-1 Plumbing truck rolls by, don't bother calling the number. Mark-1 absolutely, definitely does not service your area.

A picture posted on Twitter by the Supporters of the Religion Front — a faction engaged in the ongoing Syrian civil war — shows an enormous gun mounted to the back of a Ford F-250 decorated with the name and number of Mark-1, a plumbing operation in Texas City, Texas. Mark-1 is known better for unclogging toilets than fighting brutal, drawn-out conflicts in the Middle East.

It's no laughing matter

As bizarre as it is, it's no laughing matter: as the picture has spread on social media, KHOU reports that Mark-1 has received angry phone calls from individuals wondering why they're supporting a bloody war worlds away. The company traded in the truck last year, which ended up going to auction; fast forward a few months, and the vehicle — Mark-1's contact information and all — somehow shows up in Syria, modified to create problems rather than solve them.

Always remove your phone number from your truck before you sell it.
