I hope he doesn't do this in public.

@Rachox is correct when she says that an OGTT can be raised if you have been eating a very low carb diet in the days beforehand, simply because your pancreas has been used to being allowed to produce a lot less insulin. Once you hit it with 75g of pure glucose during the OGTT it is still asleep, producing very little insulin. It needs time to wake up, hence a raised 2 hour reading. I don't know if this was the case with your test.
