A virus walks into a bar, and sits down. The bartender tells him, "We don't serve your kind here."

The virus is momentarily taken aback by this unexpected and blatant display of bigotry, the likes of which he's only seen in history textbooks.

For a brief moment, he considers the bartender. What kind of life experiences would shape someone into such a pathetic piece of garbage? What happened to this man to instill in him such an absolute dislike of viruses? All this goes through his mind in a matter of seconds.

The virus senses an awkward silence about to fall. Purely on instinct, he responds with an attempt at humor, and says, "Well, you're not a very good host."
