The right answers are sometimes closer than you think - all this contestant had to do was look down at his t-shirt.
The contestant, named only as Alberto, was on the popular Ahora Caigo (Now I fall) show in Spain in which contestants go head-to-head for a top prize of 100,000 euros.
Host Arturo Valls had asked him the question: "What is Steve Rogers in the Avengers? 'Doctor', 'Sir' or 'Captain'."
The answer did not appear a difficult one for a fan of Marvel comics and movies, such as Alberto, especially one who had the right answer - Captain America - all over the front of his t-shirt.
