We claim the ornamental design for a cap with teeth in bill, as shown and described.
FIG. 1 is a perspective view of a cap with teeth in bill.
FIG. 2 is a front view of a cap with teeth in bill.
FIG. 3 is a side view of a cap with teeth in bill.
FIG. 4 is a rear view of a cap with teeth in bill; and,
FIG. 5 is a top view of a cap with teeth in bill.
The broken lines showing of the person's head and neck in FIG. 1 are for the purpose of illustrating environmental matter and form no part of the claimed design. In the figures, the broken lines that occur on either side of the gore seams represent stitching and are part of the claimed design.
