Example 1
Teacher: Give me your homework.
Student: Here's my homework; (pretends to hand it over) I wrote it on magic
paper that only wizards can see and touch.
Teacher: That excuse is untenable. You still get a zero and detention.
Example
2Person A: I'm telling you;
Jesus really exists in the communion wafers of the Eucharist. Transubstantiation is irrefutable because sacred scripture and church doctrine supports it.
Person B: No, That's not irrefutable, that claim is untenable! The church has no palpable
proof themselves, only
St. Thomas Aquinas's word games. All that faith in your head has mushed the brain out of your ears.
Person A: Heathen! You know in your heart that
God is
real and that he loves you!
Person B: That's also untenable. But I'm not saying that I can prove you to be wrong.
