Comment here with a topic, any topic, and I will write a limerick about it for you.
Whether or not you're familiar with this, you can look at the various examples from 2008, 2009, 2010, 2011, 2012, and 2013 for amusement and inspiration.
Please keep it to one topic per comment--though you can comment more than once, and there's no deadline for submitting a request. As such, feel free to drop back in whenever you're in the mood for a limerick. :)
If you don't have a LiveJournal account or other means of logging in, please let me know how you got here, and make sure to sign your "Anonymous" comment(s) before submission.
I know I can be notoriously slow at replying to comments sometimes, but (as with previous editions of this challenge) I'll do my best to be as prompt as possible on this.
With some luck (of the Irish or otherwise), I look forward to seeing your creative responses.
