You really have to respect this as what may just be a tingle shock to you might have real bad results to someone else or a small animal etc... UNPLUG your cables until you figure out what is wrong...
Two things to check... You have to be sure your are using all three conductors. Sometime folks cut off the GROUND PIN on the extension cords for some reason.
Then you need to check to see if the receptacle is wired properly... I use one of those CIRCUIT TESTERS from LOWES plugged into the 120VAC Receptacle in the house side... It will tell you the ground is not connected properly.
I also always use a 10 gauge (10-3) HD contractor grade extension cord... However a 12 GAUGE will work also. The smaller gauges red/orange 16-gauge cables from the WALMART is too small and will get hot on you especially if you are using your air conditioner.
I also always use the RV30A-15A LONG DOGBONE type RV adapters that looks like this..
Using the small round adapters would always get hot for me and eventually will burn up your good cords...

I have this same tester. IMHO the best thing you can buy for your RV.
It 'clearly' tells you what is wrong so you know what to look for. I actually LEAVE this tester plugged in, 'inside' my RV so if anything changes I know right away. It's plugged in above the sink.
Sounds like you have an 'open ground' where YOU become the ground.
As a side note I too most certainly would NOT allow your children to be messing with what could be a dangerous electrical problem.
