This was on the T-shirt of an older (mayhap middle-aged) gentleman in the row in front of me at the opening Eucharist of Diocesan Convention. I thought it was one of the most succinct and least brazen t-shirts ever. During the Peace, my dad, who is made of awesome (oldfrodo, not that he ever posts anything), spoke across my mom (queenpeil, who is pretty nifty herself, even if she does neglect to pass hugs around the table for me) said to the gentleman:

"I like your T-shirt."

My dad is cool.
