Science jokes! A proton walks into a bar. Strolls up to the bartender and says ""I don't care what you serve me, but I want the most expensive drink you offer."" The bartender looks at him quizzically. ""You sure about that, buddy?"" **""I'm positive.""** A cute little neutron walks in right after him. ""I'll have what he's having,"" she says. The bartender pours another glass, slides it over with a wink. **""No charge.""** A mole walks into the same bar, sweating profusely. ""I just worked the hardest I've ever worked. I need a drink. No, I need a lot of drinks. Just keep them coming."" The bartender asks, ""How many are you going to have?"" **""6.02 times 10 to the 23rd.""** **edit** Proton, not protein. Thanks /u/The_Appollo
