Three weeks ago: I put a dish in the drying rack.  It slipped out and hit a wine glass sitting next to the rack.  The glass shattered.  I told my roommate that I would get another glass to replace the one of his that I broke.

Two days ago: I finally got around to buying the replacement glass.  I couldn’t remember exactly what type of glass I broke, so I got two different types.

Yesterday: I gave the replacement glasses to my roommate.  They got placed on the counter.

Today: My roommate was putting away groceries.  He turned around suddenly and knocked the two new glasses onto the floor.  They both shattered.  The tags were still on the bases of the broken glasses.

Yes, the glasses that were purchased to replace the broken glasses were themselves broken.  Oh, the irony.
