grammaticality - "There's too many numbers" vs "There are too many numbers"

When people use plural nouns after the word "there's", for example:

There's too many numbers.

it makes me a bit frustrated. I try to correct it by using "There are," but it still happens sometimes to me (the "there's" situation). Do you think that there are is the correct usage option? People usually use there's, as I said.

If you want always to write, "There are too many damn fools on the Internet", then no one is stopping you. FWIW you have my blessing. But if you want to mount a crusade against what Marius calls the informal & casual "There's too many damn fools", then I think you have a job for life.
