Don't Stop Retrievin' T-Shirt
They're man's best friend for a reason. They've been selectively bred specifically to bring you stuff. Whether it's a recent hunting kill, your slippers, the paper, or a beer - they're more than happy to grab it for you. Next time your best friend does your leg work for you, pat them on the head, give 'em a treat and tell 'em "Don't Stop Retrievin'!"
