I claim the ornamental design for a toilet, as shown and described.
FIG. 1 is a perspective view of a toilet;
FIG. 2 is a front view of the toilet shown in FIG. 1;
FIG. 3 is a rear view of the toilet shown in FIG. 1;
FIG. 4 is a side view of the toilet shown in FIG. 1;
FIG. 5 is another side view of the toilet shown in FIG. 1;
FIG. 6 is a top view of the toilet shown in FIG. 1; and,
FIG. 7 is a bottom view of the toilet shown in FIG. 1.
In the drawings, the broken lines depict unclaimed portions of the toilet. The dot and dashed lines represent a boundary between the claimed and the non-claimed portions and form no part of the claimed design.
