Bleach and Vinegar yield poisonous Chlorine gas.
Something even worse is Bleach and a lot of Ammonia. It yields poisonous Chloramine gas plus poisonous and potentially explosive Hydrazine (rocket fuel).
There is nothing funny about being stupidly lethal. You could kill a room full of kids pretty quick.
I am not much of a chemist.
I did know not to mix bleach & household cleaners.
Hydrazine and its derivatives are not very stable and will react with any oxidizer in an explosive or near explosive manner.
