A brand new day.

 In that case, he can fake it.

He can't help but be fresh.

Puttin' on the Ritz.

 Meaning no disrespect to Bobby Burns...

But the times they are a-changing.

Bear trap.

Escape-proof by design and material.

Rusted shut by all indications.

In the words of Stan Lee.

 As years go, it seemed never-ending, until it didn't.

Poor kid, you don't know the half of it.

(Strictly speaking, it's  'Nuff said.)

Taking care of business.

 He has discovered that Cheaper and Easier

Make good business.

The big lug.

 Good used tires are hard to come by.

It's a poor workman who blames his tools.

Feeling Punchy.

 That was Ross Martin's line...

 In the Hawaiian Punch commercials.
