When you go to kiss your grandma goodbye and she slips you the tongue.
A lesbian with a hard on.
A. They're all laid with tongue and groove.
Going to kiss your grandmother goodnight and she slips you the tongue.
One wags it's tail, while the other tags a whale
A slipped disk.
He goes to a bar and slips somebody a Rupee, then gives them a Franc and some Deutsche Marks.
When the damn coffin lid falls and hits you in the head.
He left lip prints on the mirror!
