As an experiment I vote that you email the company somehow with your pic (well, preferably a clearer one) and your story. I wouldn’t be surprised if they just sent you a new one on a lark.
Could a lark even carry a mug? Maybe an African one.
Disclaimer: MOL, I know this isn’t the mug you broke and want back, but it is one hell of a mug:
An African mug?
Have you tried Gorilla Glue?
So far, the best reccomendation is, if you hang about in bars, and I think you do, to ask 'em if they have any stuffed somewhere. Swag is swag, sometimes they just pile it in the corner.
Or you could write to Jameson. It can’t hoit.
Whoa. Gorilla glue expands big time and would seap out the cracks.
Standard Super Glue is your best bet, though I would not put too much hope on it.
Sorry. 
If you do write to Jameson, make sure you make up an awesome story about how you broke it. Probably involving some fool insulting the quality of their whiskey, and you accidentally guiding the mug in the general direction of their face.
Contacting local bars is probably not a bad idea either. Other than that… just keep vigilant.
I’m only coming back to this thread to acknowledge that you have added MOAR WIN to it.
You just might be the sweetest man on the planet. Even if your brother doesn’t have one, you are an absolute dear for even asking him to help out a random person from the internets.
Ha! Immediately upon viewing this post, I knew I’d seen this already, as the link was grey. I have been scouring tirelessly.
I shall e-mail Jameson; that never even occurred to me. I think my mind defaults to “don’t even bother” when dealing with large enough of a company. True story: As I was writing this post, I thought to myself, “I need caffeine,” reached for my Jameson mug, then thought, “Oh yeah…”
It could grip it by the handle.
Until you get a new mug you will just need to drink your Jameson sans coffee.
Heh. I don’t put no stinkin’ coffee in my whisky!
So right now, I am drinking tea from a styrofoam cup. This feels wrong.
Another possible source is to contact your local liquor distributor. That looks like the swag they have lying around the office. Maybe you can sweet-talk the distributor out of one.
If I had a dime for every time I’ve heard that --------------- never mind.
I frequent a fair number of bars so I’ll ask around.
Save this image and upload it here with the “add art” button.
Yes, I know I rock.
I’m there right now messing around. Can’t get the colors right! Someone just walked by and saw me designing my mug and said, “Oh you.”
Well I WAS searching for a Jameson cup but Jenna Jameson pictures kept showing up and then this video…and…uh…what the hell were you looking for again?
A coffee mug. A plain, dark green coffee mug that reads “Jameson Irish Whiskey” exactly like in this image. I’ve got some leads from some extremely sweet and helpful folks here, and my fingers are crossed. Thank you for the condolences, all. I’m still grieving, but I will make it through.
Hm. It seems **MeanOldLady **that a plea on your behalf has been made to Jameson. So now we wait and see…
I’m going into town today. I’ll have a look in some gift shops and see what I can see.
