Matt Damon asked his friends what they were planning for his birthday. 
They told him "We bought a kazoo". 
You can hum during my birthday.
Kazoo'd be great.
What do you call ten kazoos at the bottom of the ocean?
A good start.
What does a kazoo and a baseball have in common?
People cheer when you hit them with a bat. 
What is the perfect weight for a kazoo player?
3 and a half pounds including the urn. 
Why do loud, obnoxious whistles exist at some factories?
To give us some sort of appreciation for kazoos.
