How do I make a multi-line heading show up as a single line in the Table of Contents?

I'm writing a document where the headings often have a line break in them for the sake of formatting. When I generate a Table of Contents, they show up as two entries on the same page instead of as a single heading.

For example, if I have a section like:

Oh My God

You're Totally Not Going to Read This Section

Section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, section text, etc.

Then in the table of centents it shows up as something like:

...

The Section Before That Section You're Not Going to Read ... 14

Oh My God .................................................. 17

You're Totally Not Going to Read This Section .............. 17

The Section After That Section You're Not Going to Read .... 20

...

When what I really want is a Table of Contents like this:

The Section Before That Section You're Not Going to Read ... 14

Oh My God You're Totally Not Going to Read This Section .... 17

The Section After That Section You're Not Going to Read .... 20

(Actually, I have a bunch of sections with titles like this all in a row, so it looks much worse than in the example.)

How do I do this: Get the Table of Contents to ignore the carriage return in the middle of the section header?
