Help me tell a joke. I don’t know how. Thanks.

I have an enormous sense of humor and laugh to myself about funny things everyday, but when someone asks me 'what's so funny?' I don't explain it in a way they think is funny!

I received a gift of a bottle of room spray and throat spray in a little bag.

I never want to taste that room spray again!'

I tried to figure out how to set this up as a joke to be funny but couldn't!  

How does one set up a joke like this???
