Your mother’s brother’s only brother-in-law is asleep on your couch. Who is asleep on your couch?

I shave every day, but my beard stays the same. What am I?

What is in seasons, seconds, centuries and minutes but not in decades, years or days?

I have cities, but no houses. I have mountains, but no trees. I have water, but no fish. What am I?

Two in a corner, one in a room, zero in a house, but one in a shelter. What am I?

I welcome the day with a show of light, I stealthily came here in the night. I bathe the earthy stuff at dawn, But by noon, alas! I'm gone.

I am first found in caves, now prolific online; I am a depiction, a drawing, a symbol, or sign. I will convey whichever mood you could wish; or for that matter, a fist, flask, or fish. What am I?

There's a day, that comes around once a year.
To celebrate the man, you hold dear.
He gave you life, love and will pick you up if you fall.
When it comes to guys like him, He's the best of all.
Who is he?

When you say goodbye, I am what you need to tie.
I come as a couple and go wherever you run.
Who am I?

Take one out and scratch my head, I am now black but once was red. What am I?
