Think nothing of it.
But, back on topic. I believe this is a very strong, malevolent curse. Case in point, according to a well regarded source (wiki), the Buffalo Bills were actually named after a male bison named "billy", hence the Bills. This is a very clear snub to the historical figure Buffalo Bill, who was a strong proponent of Native American rights. Thus, the name the Buffalo Bills is basically an affront to Native American rights.
