Combine the Tennessee Honey, Kahlua, half and half in a cocktail shaker filled with ice. Shake until cold.
Melt the chocolate and spread onto a shallow plate. Swivel the rim of the glass in the melted chocolate to get a nice thick coat. Allow to set for 5 to 10 seconds, then sprinkle with graham cracker crumbs.
Strain the cocktail in the prepared glasses over ice.
