Memory of the UK !?

I came across those below when I visited the UK this past Spring. Nothing to do with Japanese tea, but I found them funny in terms of English!

"Traffic Jam" jam! I wonder how it tastes like.......:-)

I didn't know "Junk" can be high class!

It has "more than" a lot to do with Japanese tea....
What does GMC stand for??? It's "Genmaicha"
