Short and Sweet:

1.  My wife refers to it as my Man-gerie, (that is "man" and "lingerie" very cleverly combined for you slow folks)  and refers to me as "El Lobo" when I have it on. (Insists that I wear it for you-know-what)

2.  I look truly Bad*ss in it.

P.S.  I have not worn it to walmart so I can not attest to the "aroused, asthmatic breathing" it is reported to cause, only for the non-asthmatic variety.

P.S (again!)  I can also bear witness to the wearer's athletic prowess being enhanced.  This explains the picture circulating the internet of Obama playing basketball while wearing said shirt.  (It also enhances certain other things, no need for Enzyte anymore)
