On George Takei’s Facebook page, this (unattributed) composition: 
Phil did in fact predict six more weeks of winter this year. Takei’s comment, functioning as a caption: “He had his Phil.” The idiom one’s fill and/or a reference to the groundhog Punxsatawney Phil. Groan. Note: I’m classifying this composition as a type of cartoon, though no actual cartooning is involved; instead, its creator has paired an image (in this case, a photograph) with some text. So it’s like the webcomic A Softer World (posting here) and the “ecards and similar cartoons” catalogued here. On the idiom, from NOAD2:
(one’s fill) an amount of something that is as much as one wants or can bear: we have eaten our fill | I’ve had my fill of surprises for one day
And on Phil, from Wikipedia:
Punxsutawney Phil Sowerby is a groundhog in Punxsutawney, Pennsylvania. On February 2 (Groundhog Day) of each year, the town of Punxsutawney celebrates the legendary groundhog with a festive atmosphere of music and food. During the ceremony, which begins well before the winter sunrise, Phil emerges from his temporary home on Gobbler’s Knob, located in a rural area about 2 miles (3.2 km) east of town. According to the tradition, if Phil sees his shadow and returns to his hole, he has predicted six more weeks of winter-like weather. If Phil does not see his shadow, he has predicted an “early spring.”
