Two men went into a restaurant. They sat at a table and the waiter came by and asked, "What do you want to drink?" The first man said, "I'll have H20." The second man said, "I'll have H20 too." The second man died.
What happened to the second man ?
Taking this as per Chemical Equations.
H2O means water. and H2O2 means Hydrogen Peroxide (a type of poison).
So first person asks for H2O and he gets water to drink. Even second person also ask for water but the way he said it pronounced as H2O2 instead of H2O too. and so Waiter gave him H2O2 i.e. Hydrogen Peroxide and so he died.
There are 57 ducks walking to a pond. On the way, 15 get lost, 26 head back, and 16 make it to the pond.
What happened to the rest?
