Okay, here's a script that adds a button to launch those Easter eggs:
Once installed, merely select the desired Easter egg from the drop-down then press the EEgg button. (Then weep for the poor puppy you could have petted/walked with that time.)
To install, click [here (Chat, Wheel of Blame and other Easter eggs install at Github)][3].
**To preview the source**, click [here (*Chat, Wheel of Blame and other Easter eggs* preview at Github)][4].
Tested on/with Tampermonkey. Should work with other decent userscript engines...
