Trish was about to leave for a gymnastic meet moments ago. Said the tire air temp monitor on her car came on. She told me she was going to check her tires to make sure they were all ok. It's pouring rain outside. Moments later, I hear her yelling, cursing, and not pleased. A soaking wet Trish comes into the bedroom and says "What the (insert impressive string of curses here) did you do to the air gauge?? It doesn't fit!!" And she produces the gauge I had just used to check my snowmobile's compression. Yep..mistook the compression checker for the air gauge. Thought it was funny!
