That's awesome Mike, but you really shouldn't have brought up limericks. Here is one I made up a while ago. Not train related, but may be worth a listen. I'm going for a walk in a minute. By the time I get back I may have ten limericks in my head.
I once made love to a gal on a cactus
you could tell that she'd had lots of practice
for I paid a price for passion you should know
I had holes in my body head to toe
while she walked away from our tryst almost scratchless
