Since me and my wife are now watching "Vikings", remembered this one.

Vikings ship is in the middle of the sea. Suddenly, a huge one-eyed bearded face appears in the sky.

"Vikings!", the face yells.

"Yes, Odin", vikings reply.

"Do you love me, vikings?"

"We do, Odin!"

"Do you believe in me, vikings?"

"We do, Odin!"

"Jump overboard!"

So, they all jump overboard and drown. A moment later, another same face appears, right near the first one.

"Loki, you bastard!"
