Got any funny greeting card ideas for triathletes?

I’ve recently launched a greeting card line for marathoners and will be rolling out the triathlon category soon. I’ve done six triathlons in my life but none recently.

I’d appreciate any insightful scenarios that only a triathlete would appreciate and understand from the standpoint of “it takes one to know one”. For examples, please see

Thanks so much for your help!

Check out the quote below. Its from the new Eastbound and Down series on HBO. This is a school principal talking to an ex professional baseball player. Check it out.

Ouch! Good one. Thanks!
