In order to rule out my brain playing tricks, I was able to replicate the effect. Then I started getting a kick out of it and shocked myself a few times for fun. Don't ask...
I'm assuming this is NOT normal oven behavior.
I'm about to give my landlord a call and would like to get my story straight before I do. What the hell is the problem here? Worn insulation on the coils? Bad oven ground? How can it be fixed? The ovens old as dirt, no self clean and the timer is busted, but generally works pretty good.
I'd like a new one, he owes me. It was the last thing in the place that didn't get updated. Is there any way I can drum up some nonsense in order to convince him it needs to go?
Thanks for anyone willing to help.

A residual-current device (RCD), or residual-current circuit breaker (RCCB) is an electrical wiring device that disconnects a circuit whenever it detects that the electric current is not balanced between the energized (line) conductor(s) and the return (neutral) conductor. In normal circumstances, these two wires are expected to carry matching currents, and any difference usually indicates a short circuit or other electrical anomaly is present. Even a small leakage current can mean a risk of harm or death due to electric shock if the leaking electric current passes through a human being; a current of around 30mA (0.030 Amps) is potentially sufficient to cause cardiac arrest or serious harm if it persists for more than a small fraction of a second. RCCBs are designed to disconnect the conducting wires quickly enough to prevent serious injury from such shocks. (This is commonly described as the RCD being "tripped".) Injury may still occur in some cases, for example if a person falls after receiving a shock.
If the landlord thinks you are enjoying getting zapped, he may put the rent up and keep the stove as a 'feature'
In my left hand was the stainless steel lid I was using to cover the pan.
In my right hand was the stainless steel spoon I was using to stir.
Coils don't have insulation, they are very bad conductors, that's why they get hot.
inside the dark metal coiled heating element on an electric stove there is an electrical resistance wire that connects the electrical contacts and gets hot when electricity flows through it. that is similar to the filament of a light bulb or the heating wire in a toaster only here the resistance wire is much larger. this resistance wire is totally surrounded by an electrically insulating material that conducts heat well (it is not thermally insulating), this is then surrounded by a durable metal tube that gets hot and you set your pans on. no electricity to the outside, only heat (if things aren't broken).

A glass-ceramic cooktop (2005)
The first technology used resistive heating coils which heated iron hotplates, on top of which the pots were placed.[12] This was subsequently developed into a spiral hollow steel tube that had a heating element running through the middle. The tube was wound in a spiral underneath the pan. Unlike the earlier iron hotplate the steel spiral was heated to red heat imparting more heat to the pan than the hotplate could.
In the 1970s, glass-ceramic cooktops started to appear. Glass-ceramic has very low thermal conductivity, a coefficient of thermal expansion of practically zero, but lets infrared radiation pass very well. Electrical heating coils or infrared halogen lamps are used as heating elements. Because of its physical characteristics, the cooktop heats more quickly, less afterheat remains, and only the plate heats up while the adjacent surface remains cool. Also, these cooktops have a smooth surface and are thus easier to clean, but are markedly more expensive.
A third technology—developed first for professional kitchens, but today also entering the domestic market—is induction cooking. This process has hitherto only heated ferromagnetic cookware directly through electromagnetic induction.[13] Recent developments have enabled non ferrous cookware to work as well, but not as efficiently as ferrous.[14] Induction stoves also have a smooth glass-ceramic surface.
