Four Blondes In A Pickup

[forgetjack]

Four blondes drive to a bar in their old pickup truck. Three sit in the cab, and one sits in the bed of the truck.
The three blondes go into the bar and order a round of shots. Almost an hour later, the fourth blonde finally joins them.
"Where have you been?" they ask.
She responds, "Well, you all forgot to open the tailgate!"
