Satchel and Susansinclair, reference geeks

Here's the last half of the final panel of today's Get Fuzzy. Note that Satchel caps the action with one of my favorite phrases. Other versions of this phrase:
1. I'll google it!
2. Let's check wikipedia...
3. I heard that story on NPR--let's look it up.
4. That's so cool--I wish I had a book for that!
