Stereotyping is bad, mmmkay

I don't agree with stereotyping. But when stereotypical behavior happens, its pretty funny. On my way to work today there was this white van holding up the far left lane. I switched lanes to pass on the right. As I'm getting closer I see the van is driving on two flat tires. I think to myself, "Only a Mexican would drive a van with two flat tires." When I got even with the van, sure enough it was full of Mexicans. Was it wrong of me to think that? Absolutely. Did I laugh when my ignorant thought was true? Out fuckin loud.
