Even though the Broncos are horrible, it's always the right time to make jokes about the Raiders:

Jack A 10 year old boy from Denver, CO, moved to Oakland, CA, with his parents.

On his first day of school, the teacher asked who in the class were Raiders fans and if they were excited to see them play the Broncos that upcoming week on Television.

Every one raised their hands except Jack.

The teacher asked, "Jack why didnt you raise your hand?"

Jack answered, "Because I'm a Broncos fan." The teacher asked "Why on earth would you
like the Broncos?"

"Well, my dad is a Broncos fan and my Mom is a Broncos fan so that makes me a Broncos fan," Jack replied.

The teacher then asked Jack, "Well, if your dad was a moron and your mom an 
idiot what would that make you?"

Jack replied, "Well, I do believe that would make me a Raider fan!"
