P → Q, and Q → R... then P → R.

If...
I pace around the first floor of our house and stop to open the fridge nearly a dozen times to see if, by a four-second glance, I can find something to eat that doesn't require any prep, (P)
then...
I will end up crossing the street in hopes of a single slice of pizza, but end up ordering a small pizza which will take 20 minutes for them to bake. (Q)

If...
I will end up crossing the street in hopes of a single slice of pizza, but end up ordering a small pizza which will take 20 minutes for them to bake, (Q)
then...
I will have to walk home from said pizza joint, wait, go pick it up, and walk home again. (R)

Therefore,
If I will have to walk home from said pizza joint, wait, go pick it up, and walk home again (R), then I am still moving around when I should be eating. (P, roughly)

I finally understand hypothetical syllogism. Good thing I took that logic class twice- life makes so much sense.
