Did someone or something fart on Mars?

The robot rover has just reported finding methane.

I swear - I never thought you'd find out.

I hear it is all the cows belching

Would spin them out if they found decaying life forms under the surface like at the tips here.
We got methane traps above some rotting deposits that capture the fuel.

Some house sites here were pulled down a few years back because of councils allowing building on the wrong old tip sites and people getting sick from methane in their homes.

Be interesting if they dug down on Mars see if its coming from below cause that shit rises.
