A middle aged gent had just finished his shower and when he entered the bedroom he looked at the full length mirror (still nude) and commented to his wife of many years who was lying in their bed, "Look at that - 6' of pure dynamite" as he flexed his muscles and sucked in his gut a bit more. She rolled over, looked at him and replied, "Yup, too bad it's only got a three inch fuse"!

...fuses are meant to  get lit, and get that, um, explosion. Right?

IF you can get to it!!
