Isn't that a Barbara Streisand movie?  

Isn't that the lint that collects in babies' belly buttons?

A wonderful ingredient

in a great soup.

Good answers below from Anthony Acosta and Thomas J. Nelson, Realtor . I sorta know

     By the time you two are finished with this series, I am going to be "up" on everything architectural!  

I remember those commercials!  "Lintel Inside"  Oh wait that was...

Where there's an opening in a wall there's a lintel above.

Honest --- I was going to give the same answer as Amanda and Jared Christiansen.    LOL   Good thing I checked this time before answering.   

What Anthony Acosta said! 

A lintel is a structural horizontal block that spans the space or opening between two vertical supports. It can be a load-bearing building component, a decorative architectural element, or a combined ornamented structural item. It is often found over portals, doors, windows, and fireplaces. 

Ha! Just had a property inspection, it's the top of the window that supports the weight of the building material over the "opening" or of  the firebox of your fireplace too I believe, but definitely windows.

That would be the belly button ... no?  Self-contained lint trap - something we never talk about or tel?

I know this one as well - I feel smart again ;)

Why do you need to know?

A common soup ingredient.

Lintel Recipe: Take 2 posts/columns, add a horizontal beam/slab across the top and you just created a lintel! [The horizontal atop the 2 posts.]

I know this one and have numerous ones in my house.

Is it a hose that is attached to the dryer?

I have no idea. I'll have to read the other answers. 

A lintel is a beam over a door or window to support the wall from sagging,  we also call it a header

A fun series of questions.

I love Jared's answer the best!

I'm sticking with Wikipedia:  A lintel is a structural horizontal block that spans the space or opening between two vertical supports.^[1] It can be a load-bearing building component, a decorative architectural element, or a combined ornamented structural item. It is often found over portals, doors, windows, and fireplaces.

another commonly used term in construction.....most often used with masonry....

wood framed lintels are called headers.... 

It's a bean, it's an overhang above a door I think.

No clue.

Sounds like an ingredient in a soup

Now I know!

Just do not bang your head

Anthony Acosta has got you covered on this one with a complete definition!

I do not know.

I just met with a seller who I showed him his lintel needed to sanding and then  painted..it has rust on it! Anthony Acosta has the right answer.

Tony and Suzanne Marriott, Associate Brokers - like Alan May 's answer - and few other funny answers.

And yes, thanks again - as I Googled about it to find out what it is.
