Tuesday Titters: Week 10, catching flies

So the spud says to me:  Wanna hear a joke, Mom?

Me:  Sure.

Spud:  What has 4 wheels and flies?

Me:  I dunno, what?

Spud:  A garbage truck.

It took me a minute, and the spud sensing the lag in the laugh track began to explain it to me.

Spud:  Get it, Mom?  A garbage truck has flies and 4 wheels.

Me laughing:  Yes, yes I get it.

In my defense, I believe I mentioned homework has stolen my life, and apparently my brain.
