When Thanos arrived at Titan Dr. Strange said "You look more like a Thanos" as if he had seen him for the first time. On the contrary Dr.Strange went ahead in time to see the possible outcomes and he must have seen Thanos in it. Is this a movie plothole?

As anyone who has seen the movie will tell you, the Eraserhead baby is the stuff of nightmares. The baby itself is famous for being somewhat of a mystery. David lynch refuses to discus the baby, what it is, how it was created, or why it's so gosh darn creepy. The few comments he has made have been cryptic. Statements such as "it was born nearby" or "maybe it was found" have lead to rampant speculation including theories that it could possibly be such things as a skinned rabbit or a cow, lamb, or even human fetus. The prop itself, nicknamed "Spike", featured several working parts making its eyes, mouth, and ears capable of independent operation. What is the baby actually made of and what evidence do we have to prove this?
What is the Eraserhead baby?

I'm always confused about the quote "Ouch, ouch, you're on my hair." in the movie Wedding Crashers. What does it really mean? When this quote is being translated into the Chinese version, it means "Stop touching my hair during sex." It just sounds ridiculous to me.
