Laughable moments or teachable moments?

I love my students dearly. That being said, there are times when frustration threatens to take over my patience. I have one 11 year-old student who has the language of about a three year old. The kids were doing an exercise with our Speech-Language Pathologist. She was giving them clues about a secret object and then they had to guess what the object was. Simple, right? Well, it was for most of my students. The afore-mentioned 11 year-old was having a tough time with it. Real life example:

Clue 1: "It is yellow"
Clue 2: "It is a fruit"
Said student yells: "a Sister!!"
Teacher redirects with clue #3: "You can peel it"
Said student yells: "THE WIND!!"

On a side note, I have heard this student use the word "banana" before and he frequently brings them to school as a snack. And yes, this student was really trying to guess this word. Maybe it was a fluke, you say? Here is the next real-life example:

Clue 1: "It lives in the ocean"
Clue 2: "It has sharp teeth"
Said student says: "A dinosaur!!"
Teacher redirects with clue #3: "It likes the smell of blood"
Said student yells: "I know! A baby!"

Could anyone out there please tell me what I, as an educator, am supposed to do with that???
