The Easy Hero

The other day at school we had to write down our hero and what we would do if they walked into our house. I got off easy because my hero is Stephen Hawking.

Explanation

The humor comes from the fact that Stephen Hawking, due to his ALS, was confined to a wheelchair and relied on technology for communication. The implication is that it would be less problematic for him to enter one's house than most other heroes that might require more accommodations.
