Ben: "Ooo, I can't wait until we watch Star...Blazer...No wait. Star...whatever tonight!"
Me: "That's not it. I'm not going to let you watch it until you get the name right."
Ben: "Aahhh...!!"
Me: "....."
Ben: "...Do you want me to make you a milk tea?"
Me: "Sure."
Ben: "You have to tell me what it is first!"
Me: "You were close with it ending in an 'ER'"
Ben: "Uhhh. *names a buncha words that end with an 'ER' that might've included bouncer and beamer* Does it start with a B? C?"
Me: "You're close."
Ben: "Wait, B?!"
Me: "No...."
Ben: "A!?"
Me: "..........."
Ben: "B!? C?"
Me: "SO CLOSE."
Ben: "D!!!"
Me: "Yes!"
Ben: "Dreamer? Drawer? Digger? Dreamer? Wait, I already said dreamer....Dipper? Digger? Star....DANCER!?"
Me: *dies laughing, tears in eyes*
Ben: "Drinker?"
Me: "There's not THAT many words that start with a D and end in an 'ER'..."
Ben: "DRIVER?! DRIVER!! STAR DRIVER!"
