Ignatieff goes to pot
That leaf looks an awful lot like this one:
The top one is the banner used on Ignatieff's site. The bottom one is an image of a marijuana leaf. Notice the striking similarities?
There are plenty of puns to use here. I used one in the title to this post. But others could have just as easily been used. Like:
Ignatieff high on renewal.
What is Ignatieff smoking?
Ignatieff plucking out the weed.
Ignatieff is your bud.
Jonesin' for Ignatieff.
And so on...
