The Muppets all have strong ties to each other and demonstrate loyalty. In fact, I had a hard time not using Fozzie and Kermit's friendship as the prime example of camaraderie. But then I thought to myself, good golly, Beaker sure takes loyalty and friendship to an all-time high. Either that, or he's a masochist in disguise. Poor Beaker endures all sorts of tests from the "genius" of Bunsen Honeydew, such as being shrunk, cloned, deflated, turned invisible, and blown up, to name a few. What makes him come back for more? Really. I'd love to know.
Since I prefer to think of the Muppets in a positive light, I have to assume that Beaker timidly comes back each time to Muppet Labs because that's just the kind of friend he is. He forgives and forgets (he must forget), even when a special elixir Dr. Honeydew has created causes his entire head of hair to pop right off. He endures electrocution on behalf of all the Muppets, yet still plods on, head smoking, body trembling, and eyes lit up like the 4th of July. Talk about the ultimate friend.
Dr. Honeydew better appreciate the kind of friend he has in his "faithful assistant" Beaker, and I think we all should appreciate those friends in our lives who demonstrate the same kind of faith in us, even when we blow them up accidentally. Because, after all, wouldn't we be gladly blown up accidentally for our friends? (provided we are well and whole in the next episode of "muppet labs", of course.)
"Meep-meep, meep-meep-meep!" -Beaker
