I saw shirts for young kids once that said (upside down) "If you can read this... Catch my calve!" Then they said the name of the calf camp and the sponsors on the back. I thought they were pretty cute.
Our 4-H club is called Prime Cuts and on the back of our shirts it says "Show the Best Eat the Rest"
i have also seen shirts with "Nothing Butt the Best" with the steers hind quarter showing
you could do a variation of "I trained when you slept" Change the trained to Blew, groomed, or maybe just "trained hair" just an idea
my skills pay the bills
We have several different shirts from years of 4-H that say things like this. 'if you can't take the heat, stay out of the ring', 'go big or go home', 'in it to win it', 'bustin' mine to kick yours', 'blood, sweat & tears..it's all about braggin' rights', that's a few..
