A bunch of bar jokes - Part I

I found this list on my harddrive. They're pretty funny :) I remember seeing them on digg, but not sure where exactly. Anyway,

A guy walks into a bar with a slab of asphalt under his arm and says, "A beer please, and one for the road."

An amnesiac walks into a bar and asks the bartender, "Do I come here often?"

A guy with dyslexia walks into a bra.

A young Texan walks into a bar and orders a drink. "Got any ID?" asks the bartender. The Texan replies, "About what?"

A pair of battery jumper cables walk into a bar. The bartender says, "You can come in here, but you better not start anything!"
