You have to understand that function calls execute immediately, not when you reference the variable storing the result of the function call.
Try this one:
score = 0
name = input("Come on down, what is your name?")
intro = (f"\nWelcome {name} to 'Dad Joke Mania' the show where you finsh the dad joke with the correct punch line!\n")
#questionpick = input("Pick a number 1 - 5...")
question1 = "Q: How to you make a space party? A:..."
question2 = "Q: What do call a well-balenced horse A:..."
print(intro)
print("Now answer this question.")
answer1 = input(question1)
if answer1 == "you planet":
print("correct")
else:
print("Inocorrect :(")
print("Now answer this question.")
answer2 = input(question2)
if answer2 == "stable":
print ("correct!")
else:
print("Inocorrect :(")
