Counterargument

"If there is no God, how do you explain that you'll go to Hell for being an atheist? It makes no sense!"

Infalsifiable

"Nobody criticizes me. That means absolutely everyone supports me. I must be doing it right!"

"Some criticize me. That means I'm upsetting certain people. I must be doing it right!"

Paradox

"The issue poses questions that can't be solved using conventional logic. For instance: what if someone went back in time and prevented himself from ever being born?"

"Uh-huh."

"Well?"

"Time travel is abortive."

"I see. We'll issue a press release condemning it as soon as possible."

Occam

"I photographed this UFO in the countryside last night. It was like a fireball blazing in the sky."

"I see."

"What do you think? Is it a meteorite, or something else?"

"Well, Occam's Razor tells us we should always prefer the simplest explanation. So, which one is likelier? That a lump of space rock has been floating around for millions of years, avoiding all that time to hit other heavenly bodies, just to fall to earth at the right time and place for you to take a picture of it?"

"Hum... if you put it that way..."

Al Pacino

"See? There's the proof you wanted! The newspapers confirm that Al Pacino does exist! Do you still doubt that he comes over to my place every Saturday to play cards?"

"See? Scientists admit that there might be life on other planets! Do you still doubt that Egyptian pyramids and crop circles are the work of alien visitors?"

Ad absurdum

"Many believe all atheists are jerks who don't respect other people's beliefs. This is not just unsopported opinion. It can be proven! Suppose there exists at least one atheist who respects other people's beliefs. Well, this atheist is disrespecting the belief that atheists don't respect other people's beliefs. Quod erat demonstrandum.

Deluge

"But— Lord! You promised—"

"Don't you listen to what you yourself preach? Doesn't your faith hold that I am all-powerful and above logic? When, in that case, I can destroy the Earth with water whenever I feel like it without ever breaking my word of not doing it again! You of little faith."

Binary logic

"As the truth table of the example clearly shows, the faith-based approach simplifies the analysis of digital circuits."
