A Big Rig Crossing a Bridge

An 18-wheeler is crossing a 4 kilometer bridge that can only support 10,000 kilograms and that’s exactly how much the rig weighs. Halfway across the bridge a 30 gram sparrow lands on the cab, but the bridge doesn’t collapse. Why not?

Since the bridge is 4 kilometers long, the halfway point would be 2 kilometers. The 18-wheeler would have used much more than 30g of fuel to drive 2 kilometers.

Come For a Ride

I go up, but at the same time go down,
Up toward the sky and down toward the ground,
I’m present tense and past tense too,
Come for a ride, just me and you.

What am I?

Three Philosophers Under a Tree

Three philosophers are taking a nap under a tree. While they’re asleep, a small boy smears their noses with red berries. When they awake, they each begin to laugh, thinking the other two are laughing at each other.

But then one philosopher stops laughing, realizing his nose is red too. How did he come to this conclusion?

Let’s call the philosopher’s A, B and C. A reasoned that B was confident his nose wasn’t red. If B saw A’s nose wasn’t red, he would be surprised that C was laughing, because C would have nothing to laugh at. But B wasn’t surprised, therefore, A correctly reasoned his nose was smeared.

If My Hand Is Forced I Can Sink Ships

I move quickly with hurried steps,
If my hand is forced I can sink ships,
I’ll cause you to shudder when driving your car,
And haul your fuel to where you are,
I’ll watch you bleed from a cut,
Add a rear and I’ll tell you what’s what.

What am I?

Scuttle. To scuttle is to scurry or run hurriedly. Scuttling is the deliberate sinking of your own ship. Scuttle shake is felt in convertibles where the passengers feel a distinct shudder. A coal scuttle is a bucket-like container to haul coal. A shaving scuttle holds hot water when you’re shaving. And adding a “rear” forms scuttlebutt, or rumors and gossip.
