Again, two unrelated things.

If my doctor can't pat his head and rub his belly at the same time, how can I trust him to diagnose my rash?

How can we trust pies to taste right when we can’t even put a man on Mars?

How can we trust our phones to charge quickly when we can’t even predict the weather with 100% accuracy?

How can Angela Bassett do the thing when the stock market is so volatile?

See, I can compare unrelated things to each other too.
