Always look before you sit, especially on a toilet.
An 8-foot-long poisonous snouted cobra has been terrorizing an apartment building in Pretoria, South Africa.
The snake was first spotted on Thursday morning inside a toilet in one of the building's apartments. The residents quickly called Barry Greenshields, a snake catcher who attempted to remove the snake from the building, according to News 24.
Unfortunately for Greenshields and everyone else in the building, he was unsuccessful and the snake slithered back down the toilet. Resident posted a clip of the extraction attempt to YouTube, stating, "we still have no idea where the snake is hiding."
According to News 24, the snake has not been seen since the incident, freaking out residents in the building.
Some residents have considered pouring boiling water or pool acid down their drains to flush out the unwanted guest. But Greenshields cautioned against those tactics.
"We have put cameras in the pipes to look for it. Residents are still worried and some of them are feeling like if it comes up they want to kill it, which is something I don't want. I hope he has left through the pipes," Greenshields told News 24.
