    Professor Proton Was Funny!

    I have little to say. Sheldon was his usual selfish self and invaded Amy's territory. Meanwhile, Raj rejected Howard's offer to appear in one of his planetarium shows. This leads to an idiotic moment that neither would do in front of other people. But there were two stellar moments when Sheldon consults Professor Proton one more time.

    Super boring episode

    This one was a total snoozefest. It's like the writers went on a vacation and so somebody had to recycle old jokes to create this filler episode.

    Not one story was interesting or any of the jokes funny. Maybe they should just copy more FRIENDS episodes. It may be shameful to plagiarize but at least those are still funny (like Stuart getting a tan like Ross, etc)

    Really?

    It was a fairly standard episode of the big bang theory. Some jokes were funny, some weren't. We know what to expect at this point. The only truly awful part was when Sheldon explains mansplaining to Amy. This show is built on stereotypes of men, women, jews, indians, and many others. For the writers to go all progressive on us is hypocritical and ridiculous.

    • Trivia
      Final appearance of Bob Newhart as Arthur Jeffries/Professor Proton. In his previous episode The Proton Regeneration (2017), Newhart also appeared in Sheldon's dream on Dagobah, expressing his wish to meet in a deli while eating a pastrami sandwich. His wish has been granted here.
    • Goofs
      In his lecture Raj states that Jupiter has 79 moons. An 80th moon was discovered in May 2018, prior to the airing of this episode (but not before the show was written.)
    • Quotes

      Sheldon Cooper: I'm having a problem in my marriage. I've upset my wife and I don't know how to make it right.

      Arthur Jeffries: And ya-and you're coming to me for advice? I-I upset my wife every time I woke up in the morning.

      Sheldon Cooper: I'm not coming to you. You're just a manifestation of my subconscious. I mean I'm actually coming to me.

      Arthur Jeffries: So you know everything I'm going to say.

      Sheldon Cooper: Yes, but it sounds wiser from you because you're old and glowing.

      Arthur Jeffries: Fine. Rule number one in a marriage - Don't go to bed angry.

      Sheldon Cooper: That makes sense.

      Arthur Jeffries: Rule number two in a marriage - If you don't recognize the shoes under your bed, they're not your shoes.

      Sheldon Cooper: Because they're her shoes?

      Arthur Jeffries: Ne-never mind. Just, just go with rule number one.
