Under what circumstances would 5V@2.1A be lethal?

Besides obviously sticking an output of 5V directly to the heart. Are there areas inside the body where resistance in ohms is so low that a 5V electric potential would be fatal?
Here we go...
I got into an argument about this with my roommate after he made a joke about sticking an lightning apple lightning cable directly up his urethra. I told him that his brilliant idea could cause a nasty shock since internal body resistance is so low. He, however, insisted that the lowest internal body resistance still sits at a few hundred ohms and 5V (5V 2.1A Charger) would not suffice to provide a dangerous current. Would it be possible for internal resistance in this area to be so low that even 5V or less would be dangerous? Say it took a path up the bladder and through the kidneys and to the heart.
Thanks, apologies for the bizarre circumstances.

Sounds like medical college grad joke. If you have multimeter, propose him to measure the resistance in his urethra. Not sure where second probe will go though. Depends on the area of medicine he is studying.

Ha ha. This really made my morning. :-) Since the + and - terminals will be very close together, I doubt that the current will travel all the way to the heart. It might result in a shock or tinkling sensation in the urethra area.

if applied for a long duration electrolysis can cause acid/alkali burns - see warnings about swallowed lithium button cells.

Except if you proceed with a surgery to apply the 5V directly on the heart, or some other vital organ, it certainly can't be lethal.
The resistance between any two accessible points on your body is either:
- Rather low, because the two points are very close together, possibly on a wet surface (e.g. the tongue... or the urethra, whatever...). So a significant current goes through, and you can feel it (it could hurt), but it won't kill you because the current takes the path of least resistance and there is no way it disturbs any vital organ because they aren't in the way.
- Very high, because the two points are far away from each other, in which case the current will be so low you probably won't even notice.
The NIOSH states "Under dry conditions, the resistance offered by the human body may be as high as 100,000 ohms. Wet or broken skin may drop the body's resistance to 1,000 ohms". "Wet or broken skin" could be the equivalent of what you have on the tongue (urethra?), so at 5V it would give 5mA. Which apparently translates to "perceptible but no muscle reaction".
